Abstract

PURPOSE: To manufacture an amorphous magnetic alloy material with superior magnetic characteristics by applying external magnetic fields to an amorphous magnetic alloy sheet or other material from two directions while heating the sheet to a specified temp., rotating the direction of the synthetic magnetic field so that induced magnetic anisotropy is made isotropic, and cooling the sheet.
CONSTITUTION: Amorphous magnetic alloy sheet or this wire 10 manufactured by very rapidly cooling an alloy consisting of transition metals and metalloids is heated and maintained at a temp. of the Curie point or below and the crystallization temp. or below in electric furnace 4. At the same time, magnetic fields H1, H2 perpendicularly intersecting each other are produced using two pairs of electromagnets 211, 212 and 221, 222, and they are applied to amorphous metal material 10. By rotating the direction of the synthetic magnetic filed of two external magnetic fields H1, H2, magnetic anisotropy in material 10 induced by the synthetic magnetic filed is made isotropic. Finally, material 10 is rapidly cooled to obtain an amorphous magnetic alloy material with superior magnetic characteritics.
