我们开发了纵向泵浦和角度相关铁磁共振技术来研究一系列 Co/Ru/Co 三层薄膜的层间交换场 H ex 的温度依赖性。我们的结果首次表明，H ex 随温度的变化大致遵循理论模型预测的 H ex∝(T T 0) sinh (T T 0) 关系。此外，在这些样品中没有观察到双二次交换项的证据。
We have developed longitudinal pumping and angular dependent ferromagnetic resonance techniques to investigate the temperature dependence of the interlayer exchange field H ex on a series of Co/Ru/Co trilayer films. Our results indicate, for the first time, that the variation of H ex with temperature follows roughly the relationship H ex∝(T T 0) sinh (T T 0) as predicted by theoretical models. In addition, no evidence of the biquadratic exchange term was observed in these samples.
