摘要

采用磁控溅射在玻璃基片上制备了BN/FePt/Ag薄膜

并在550℃真空退火30 min.用振动样品磁强计和X射线衍射仪研究了薄膜的磁特性和微观结构.结果表明:BN的厚度影响了BN/FePt/Ag薄膜的有序度和矫顽力

而且BN的添加有效地抑制了FePt粒子的长大

较薄的BN更有利于FePt由FCC向FCT相转变.此外

Ag的位置对提高[BN/FePt]5/Ag薄膜的垂直取向有一定的影响

总厚度为3.75 nm的Ag掺杂在BN与FePt之间要比在顶层更利于FePt垂直取向.

Abstract

BN/FePt/Ag thin films were deposited by magnetron sputtering on the glass substrates

then annealed at 550 ℃ for 30 min in vacuum.The vibrating sample magnetometer and the X-ray diffraction meter were applied to study the magnetic properties and microstructures of the films.Results indicate that BN-doping plays an important role in improving the order parameter and the coercivity

the addition of BN reduces the grain size efficiently

and the thinner BN is more beneficial for phase transformation of FePt from FCC to FCT.In addition

it is found that the location of Ag can affect the improvement of perpendicular orientation in the ·/Ag thin films.It is easier for perpendicular orientation in FePt films when Ag with the thickness of 3.75 nm is located between FePt and BN rather than in top layer.
