摘要

本研究使用带有微尺度IrMn层的自旋阀的巨磁电阻(GMR)来确定交换偏置效应。样品采用磁控溅射法制备。本文重点介绍了GMR、交换场和矫顽力场的5k测量结果。测量了IrMn厚度对矫顽力场和交换场的影响，发现对于IrMn层/spl les/12 /spl Aring/，矫顽力场大于交换场。

Exchange bias and giant magnetoresistance in spin valves with pico-scale antiferromagnetic layers

This work uses the giant magnetoresistance (GMR) of spin valves with pico-scale IrMn layers to determine the exchange biasing effects. The samples were prepared by magnetron sputtering. This paper focuses on the results for the 5 K measurements of the GMR, exchange field and coercive field. The coercive field and exchange field are measured as a function of IrMn thickness and it was found that for IrMn layers /spl les/12 /spl Aring/, the coercive field is larger than the exchange field.
