利用有序和无序相变，我们得到了Fe50Pt50交换弹簧薄膜磁体。Fe-Pt薄膜由软磁无序相和硬磁有序相组成。薄膜的剩磁、Ir、矫直力、Hc和(BH)最大值分别约为1.05T、500kA/m和130kJ/m~3。与各向同性Fe50Pt50合金0.7T的理论值相比，制备的薄膜的剩余磁化强度有所提高。与基本由有序相组成的Fe-Pt薄膜相比，上述薄膜具有更好的回弹性能。
Usage of order and disorder phase transformation enabled us to obtain Fe50Pt50exchange-spring film magnets. The Fe–Pt films were composed of soft magnetic disorder and hard magnetic order phases. The values of remanence, Ir, coercivity, Hc, and (BH)maxin the film were approximately 1.05T, 500kA/m, and 130kJ/m3, respectively. The remanence of the prepared film was enhanced compared with theoretical value for isotropic Fe50Pt50alloy, 0.7T. We also confirmed that the above-mentioned films have a superior spring-back property compared to that of Fe–Pt films which are almost composed of order phase.
