摘　　要：采用真空蒸镀法在玻璃基片上制备具有巨磁阻抗效应的单层FeS iB薄膜.通过改变驱动电流方向和外磁场方向,得到4种测量巨磁阻抗效应的方式.通过比较发现,只有当外加磁场和单轴磁各向异性方向垂直时才有比较明显的巨磁阻抗效应的出现,并比较了磁各向同性和磁各向异性FeS iB薄膜的巨磁阻抗效应.验证了用真空蒸镀法能够制备具有巨磁阻抗效应材料的可行性.The single-layer FeSiB film which had giant magneto-impedance effect was prepared in glass substrate by vacuum evaporation. Via changing the direction of drive current and external magnetic field, four modes of measuring giant magneto-impedance effect were obtaison. By comparing, it was found that only when the direction of external magnetic field and uniaxial magnetic anisotropy was apeak, there was an obvious appearance of GMI effect. Consequently, the feasibility of preparing the material which had giant magneto-impedance effect by vacuum evaporation was proved by comparing the GMI effect of magnetic isotropic and magnetic anisotropy.
