The preparation method of Tb-Fe-Co ternary RE alloy magnetic nanometer film
Technical field
Technical solution of the present invention includes the manufacture of multielement rare earth alloy magnetic nanometer film, specifically Tb- The preparation method of Fe-Co ternary RE alloy magnetic nanometer film.
Background technique
In the up-to-date technology revolution using information, the energy, material as pillar, information-recording material plays very important work With.It is repeated in recording medium material erasable, magnetic recording media and Magnetooptic recording medium are most wide materials with the most use.Magnetic Optical memory material is that a kind of magnetic write-in light using Kerr magnetooptical effect reads out record, rewriting, the carrier material for deleting information. It has converged the advantages of optical storage and magnetic storage, is widely used to national management, military affairs, aerospace, petroleum mineral products, traffic Etc. needing large-scale data real-time collecting, record, storage and the field of analysis.Remember generally, for information storage magneto-optic Recording medium material should at least meet following requirement:
(l) stronger Kerr magnetooptical effect.The Kerr magnetooptical effect the strong more is easy to the access of information, and sufficiently large Ke Er turns Angle so as to read information using Ke Er and Faraday effect, and wipes information by the formation in inverse area.
(2) higher perpendicular magnetic anisotropic;
(3) big coercivity is to provide high storage density.
(4) good uniformity and low surface disturbance;
(5) suitable Curie temperature, Curie temperature Tc is about between the range of 400K-600K;
(6) domain structure has long-time stability;
(7) lower film deposition temperature and high deposition velocity.
Due to the alloy amorphous film Tb-Fe-Co of rare earth-transition race have big magnetic anisotropy, strong ferromagnetic property and Suitable Curie temperature (500K), is widely paid close attention in terms of magnetooptic recording with storage.On preparation method, generally adopt It is prepared with physical methods such as vacuum evaporation and magnetron sputterings, but performance due to recording medium film and uniformity are strongly dependent on The many factors such as sputtering power, target-substrate distance, gas pressure, back end vacuum degree make these methods there are at high cost, low efficiency, sink The disadvantages of lamination composition is not easy to control.And electrochemical deposition method the biggest advantage is to can by control electrolyte composition and Deposition process conditions adjust the composition of alloy deposition film, are very suitable to the alloy material of preparation heterogeneity.
Using there are two types of the common solution systems of electrochemical deposition, one is aqueous solution, another kind is ionic liquid.Ion Liquid refers to the organic liquid substance being composed entirely of ions under room temperature and similar temperature, also referred to as room temperature molten salt.Matching It first has to prepare ionic liquid when electrolyte processed, chemicals used is then dissolved in the electrolysis that ionic liquid could be made required Liquid.This liquid must be carried out when preparing in the vacuum drying glove box full of protective gas, it is desirable that ionic liquid cannot There is the doping of little water, is otherwise easy to cause the failure of an experiment, institute's poor controllability in this way, at high cost, improper high-volume Production.Again since ionic liquid is room temperature molten salt, viscosity is big, therefore exists and be easy lacking for obstruction AAO form plate hole when depositing Point.And metal ions in aqueous solution, environmental condition require low, viscosity is small to be not easy to plug, and deionized water raw material is easy to get into This is low, therefore merits our study.
Currently, electrochemical deposition rare earth alloys carry out mostly in solion, such as Gong Xiaozhong is in low temperature molten salt Sm-Co nano wire [Gong Xiaozhong, Tang Jiaoning, Li Junqin, etc. rare earth samarium cobalt permanent magnet are prepared for using direct current deposition method in system The electro-deposition preparation of function alloy film and magnetic performance, China YouSe Acta Metallurgica Sinica, 2007,17 (5), 750-756.], Yang Peixia Electrochemical deposition is used to be prepared for Co nano wire [Yang Peixia, An Maozhong, Su Caina etc., in ionic liquid Deng in solion The electro-deposition behavior of cobalt, Acta PhySico-Chimica Sinica, 2008,24 (11): 2032-2036.], what these were prepared in solion receives Rice noodles shape is generally irregular, and the hole of AAO template is easy to block during the deposition process, under the quality for leading to nano wire film Drop.Former, to deposit Determination of multiple metal elements in nano wire, the method for being typically employed in alternating deposit in different solutions, The method that laboratory where the present inventor uses direct current electrochemical deposition, in Sm-Co solution and Fe-Co solution alternately Deposition is prepared for Sm-Co/Fe-Co biphase line.Although this method can make nano wire become multicomponent alloy nano wire, It is due to alternating deposit, nano wire uneven components, Sm-Co and Fe-Co are distributed in nano wire at section, to affect film The raising of performance.
Summary of the invention
It is an object of the present invention to be directed to the deficiency of current multielement rare earth alloy deposition method, a kind of Tb-Fe-Co ternary is provided The preparation method of rare earth alloy magnetic nanometer film.This method is to be prepared in aqueous solution using the method for electrochemical deposition The method of Tb-Fe-Co nano wire film, by the way that glycine to be added in Tb-Fe-Co solution system, glycine and Tb form network Object is closed, reduction potential is shuffled, while increasing pH value, weakens evolving hydrogen reaction, thus by Tb3+It is restored from solution.Method work Skill is simple, and at low cost and success rate is high, and it is heavy alloy can be adjusted by control electrolyte composition ratio and deposition process conditions The composition of integrated membrane.
