| 摘 要： | 采用直流磁控溅射方法制备了Fe/Pt多层膜和FePt单层薄膜，再经不同温度真空热处理得到 了有序相L100-FePt薄膜.通过x射线衍射谱和磁性研究表明，FePt单层薄膜需 要在500℃ 以上热处理，才能开始有序化转变，而Fe/Pt多层膜可以降低FePt薄膜有序化温度.［Fe(1 5nm)/Pt(15nm)］1313薄膜在350℃热处理后，有序度已经增加到 06，相应矫 顽力达到了501kA/m.多层膜化促进有序化在较低的温度下进行，这是由于热处理过程中多

| Abstract: | Fe/Pt multilayers and FePt thin films were prepared by DC magnetron sputtering. The as-prepared samples were subjected to vacuum annealing at temperatures in t he range of 300—550℃. The multilayered structure is an effective approach fo r reducing the ordering temperature of FePt. The ordering parameter S is evaluated to be 06, and correspondingly the coercivity is evaluated to be 501kA/m in ［Fe(15nm)/Pt(15nm)］1313 multilayers annealed at 350℃ for 20min. Relatively low ordering temperature for the multilayer is due to the e xtra driving force of ordering process caused by the vanishing of the multilayer interface at annealing. |
