【Abstract】 The ribbon of FeCoNiCuSiB amorphous alloy is prepared by the double roller type quenching method. After strand annealed in longitudinal magnetic field the magnetic properties of the alloy, such as saturation magnetization Bs, permeability ue and zeromagnetostriction (λs≈0) of the alloy are greatly improved. The alloy can be successfully used in manufacturing the core in the magnetic head of recording and reproducing cassette. The magnetic head thus manufactured works well not only in conjunction with common tapes but with metallic tapes as well.更多还原
