Abstract Three-layer thin films of spin-valve type Co/Сu/NixFe100-x at x = 20–80 at.% were prepared by electron-beam sputter deposition. The investigated phase state and magnetoresistive properties were done for as-deposited and annealed to 400, 550, and 700 K films. The measurements of field dependences of magnetoresistance were held at different temperatures. It was demonstrated that phase state, crystal structure, and magnetoresistive properties of Co/Сu/NixFe100-x systems strongly dependent on both NixFe100-x composition NixFe100-x and heat treatment conditions.

自旋阀式三层薄膜的结构和磁阻特性

摘要 通过电子束溅射沉积制备了 x = 20–80 at.% 的自旋阀型 Co/Сu/NixFe100-x 三层薄膜。对沉积后的 400、550 和 700 K 薄膜进行了研究的相态和磁阻特性。磁阻的场相关性的测量在不同温度下进行。结果表明，Co/Сu/NixFe100-x 系统的相态、晶体结构和磁阻特性强烈依赖于 NixFe100-x 成分 NixFe100-x 和热处理条件。
