Definitions

  • the invention consists of the fabrication of thin (metallic nucleus diameter below 10 ⁇ m) microwires with determined chemical composition containing Co, Fe, Si, B, C with additions of Ni, Mo, Cr, Zr, Hf with determined relation between metallic nucleus diameter and glass coating thickness.
  • the present patent as expressed in its title of the present description, consists of a method of fabrication of thin (metallic nucleus diameter below 20 ⁇ m) microwires with determined chemical composition containing Co, Fe, Si, B, with additions of Ni, Mo, Cr, Zr, Hf, C with determined relation between metallic nucleus diameter and glass coating thickness.
  • the present patent is closely related with previous Spanish patent "Amorphous glass-coated misrowires as an element of magnetic sensors based on the magnetic bistability, magneto-impedance and as material for the protection from the radiation.” (Ref. P200202248) [3], but paying special attention to the GMI effect (absolute value and tensor components) in thin wires (with diameter of metallic nucleus below 20 ⁇ m).
  • Microwires are manufactured by means of a modified Taylor-Ulitovsky process [3,4] based on direct casting from the melt, as schematically depicted in Fig. 1 .
  • a few grams of the master alloy with the desired composition is put into a Pyrex-like glass tube and placed within a high frequency inductor heater.
  • the alloy is heated up to its melting point, forming a droplet.
  • the portion of the glass tube adjacent to the melting metal softens, enveloping the metal droplet.
  • a glass capillary is then drawn from the softened glass portion and wound on a rotating coil.
  • the molten metal fills the glass capillary and a microwire is thus formed where the metal core is completely coated by a glass shell.
  • the amount of glass used in the process is balanced by the continous feeding of the glass tube through the inductor zone, whereas the formation of the metallic core is restricted by the initial quantity of the master alloy droplet.
  • the microstructure of a microwire depends mainly on the cooling rate, which can be controlled by a cooling mechanism when the metal-filled capillary enters into a stream of cooling liquid (water or oil) on its way to the receiving coil.
  • the recent tendency in miniaturization of the magnetic sensors requires the development of extremely thin composite wires produced by the Taylor-Ulitovsky method (1 ⁇ 30 ⁇ m in diameter) consisting of metallic nucleus coated by glass.
  • Recent significant progress in tailoring of magnetically soft Co-rich glass coated microwires with metallic nucleus diameter of about 20 ⁇ m fabricated by this method enabled to enhance significantly the GMI ratio (up to about 600%) [2].
  • the AC current frequency should be high enough (usually above 100 kHz) in order to observe significant change of the electrical impedance.
  • the sample holder should have special design and the electrical cables should be as shorter as possible and should possess special HF specifications.
  • the GMI effect was interpreted in terms of the classical skin effect in a magnetic conductor assuming scalar character for the magnetic permeability, as a consequence of the change in the penetration depth of the ac current caused by the dc applied magnetic field.
  • ⁇ is the electrical conductivity, f the frequency of the current along the sample, and ⁇ the circular magnetic permeability assumed to be scalar.
  • the dc applied magnetic field introduces significant changes in the circular permeability, ⁇ . Therefore, the penetration depth also changes through and finally results in a change of Z [1, 5,6].
  • the magnetoelastic anisotropy plays the most important role and must be minimized.
  • the magnetoelastic anisotropy is essentially determined by the magnetostriction coefficient, ⁇ s and internal stresses, ⁇ i : K me ⁇ 3 / 2 ⁇ s ⁇ i ,
  • the magnetostriction constant depends mostly on the chemical composition and is vanishing in amorphous Fe-Co based alloys with the content of Co/Fe ⁇ 70/5 [2].
  • This "scalar" model was significantly modified taking into account the tensor origin of the magnetic permeability and magneto impedance [7,8].
  • the GMI of thin microwires is smaller than in thicker conventional wires, but increasing the frequency GMI effect significantly increases, exhibiting much higher GMI effect at high frequencies and the shape of the Z(H) dependence at least for Co-rich materials is typical for the materials with circular magnetic anisotropy, i.e. with the a maximum at certain dc axial magnetic field ( Fig. 2,3 ).
  • the glass-coating technology gives rise to the internal stresses due to the difference in the thermal expansion coefficients of the glass coating and metallic nucleus. This difference in the fabrication technique results in the different magnetic anisotropy in the surface and in different frequency dependence of the GMI effect.
  • the present patent deals with a method of a method of fabrication of thin (metallic nucleus diameter below 20 ⁇ m) microwires with determined chemical composition containing Co, Fe, Si, B, C with additions of Ni, Mo, Cr, Zr, Hf with determined relation between metallic nucleus diameter and glass coating thickness.
  • the GMI effect is related intrinsically with the hysteresis loops of the samples.
  • the hysteresis loops depend on many factors, such as the metallic nucleus composition which is closely related with the magnetostriction constant, the geometrical parameters (diameter of the metallic nucleus, total diameter of microwires).
  • Effect of the metallic nucleus composition on hysteresis loops of microwires is reflected in Figs.4 .
  • Fig. 5 shows the effect of the metallic nucleus diameter on hysteresis loop of the microwire with the same composition. As can be observed, the magnetic softness deteriorates when the metallic nucleus diameter becomes thinner.
  • FIG.6 Axial hysteresis loops of studied Co 67.05 Fe 3,84 Ni 1,44 Si 14,47 B 11,51 Mo 1,69 microwire with metallic diameter of 8.5 ⁇ m is presented in Fig.6 .
  • excellent magnetic softness with coercivity of the order of 4 A/m has been achieved in this microwire in spite of its reduced diameter (only 8.5 ⁇ m).
  • the GMI effect of as-prepared Co 67.05 Fe 3,84 Ni 1,44 Si 14,47 B 11,51 Mo 1,69 measured at frequencies, f , up to 500 MHz is shown in Fig.7 .
  • the shape of the DC magnetic field dependence of the GMI ratio is typical for the samples with small and negative magnetostriction constant with circular magnetic anisotropy, i.e. with a maximum at certain DC axial magnetic field, H m .
  • a maximum value of the GMI ratio, ⁇ Z/Z max achieves about 180% at about 200 MHz. Frequency dependence of the ⁇ Z/Z max is shown in Fig.8 .
  • Fig.9 shows the imaginary part the impedance, X, measured at different frequencies.
  • Fig.10 shows, that heat treatment conditions (annealing temperature in this concrete sample) play an important role for tailoring of the GMI effect in glass coated wires.
  • stress annealing for 40 min at different temperatures (as indicated in Fig.12 : 1- 265°C; 2- 275°C and 3- 400°C) strongly affects the GMI ratio of Fe 74 B 13 Si 11 C 2 microwire, measured at the same conditions (11 MHz).
  • the GMI ratio depends on the samples geometry, as shown in Fig.11 for Co 67.05 Fe 3,84 Ni 1,44 Si 14,47 B 11,51 Mo 1,69 . Samples with metallic nucleus diameter from 8.96 till 9.89 ⁇ m and total diameter from 10.29 till 11.94 ⁇ m are studied. Samples geometry affects not only GMI ratio but also imaginary part the impedance, X, measured at the same frequency (300 MHz) through the effect of the internal stresses on the magnetic anisotropy. Such dependences for the same samples as in Fig.11 are shown in Fig.12 .
  • the values of the GMI ratio, ⁇ Z/Z max and the hysteresis loop depend on the microwires dimensions: metallic nucleus diameters and thickness of glass coating, as presented in Fig.5 and Fig.11 .
  • the absolute value of the GMI ratio of stress annealed of Fe 74 B 13 Si 11 C 2 glass-coated microwire subjected to stress annealing for 40 min depends on annealing temperature (between 265°C and 400°C), such as presented in Fig.10 .
