摘要

采用直流磁控溅射方法在Si基片上制备[Fe/Pt]n薄膜,利用X射线荧光光谱仪(XRF)、X射线衍射仪(XRD)和振动样品磁强计(VSM)分析薄膜的组分、结构和磁性。研究结果表明:[Fe/Pt]n薄膜经过600 ℃快速热处理,得到了L10-FePt薄膜。对于[Fe (x nm)/Pt (0.5 nm)]n薄膜,当Fe层厚度为0.7 nm时,薄膜的有序度最大,平行膜面和垂直膜面的矫顽力均最高;对于不同调制周期的[Fe/Pt]n薄膜,有序度随调制周期先增大后减小,平行膜面的矫顽力均高于垂直膜面的矫顽力,当调制周期为2.4 nm时,薄膜平行膜面的矫顽力最大。

Abstract:

[Fe/Pt]nfilms were deposited on Si substrate using dc magnetron sputtering. The composition, structure and magnetic properties of the films were analyzed by X-ray fluorescence spectrometer (XRF), X-ray diffractometer (XRD) and vibrating sample magnetometer (VSM). The results show that [Fe/Pt]nthin films have been obtained by rapid heat treatment at 600 oC. For [Fe (x nm) / Pt (0.5 nm)]nfilms, as Fe layer thickness is 0.7 nm, the order degree of the film is the largest, in-plane and out-of-plane coercivities are the highest. For [Fe/Pt]nfilms with different modulation periods, the order degree increases first and then decreases. The in-plane coercivity is higher than that of out-of-plane. When the modulation period is 2.4 nm, in-plane coercivity of the film is the largest.
