摘要

摘要合成了厚度为 202 nm 的钯铁合金外延薄膜，铁的浓度从 2%到 10%不等。测量了薄膜中自旋波共振谱的温度依赖性。模拟了驻留自旋波的光谱。根据理论光谱与实验数据的相关性，得出了归一化交换刚度、有效磁化与饱和磁化之比以及表面自旋针销系数的温度相关性。

Features of the Temperature Dependence of the Spectra of Spin Waves in a Thin Pd–Fe Film with Gradient Composition

An epitaxial film of a Pd–Fe alloy with a thickness of 202 nm was synthesized with an iron concentration varying in depth from 2 to 10 at %. The temperature dependence of the spin-wave resonance spectra in the film was measured. The spectra of standing spin waves were simulated. From the correlation of the theoretical spectra with the experimental data, the temperature dependences of the normalized exchange stiffness, the ratio of effective magnetization to saturation magnetization, and the surface spin pinning coefficients were obtained.
