在坡莫合金薄膜中观察到自旋驻波共振。用Kittel自旋钉扎边界条件和良导体的ω-k色散关系对结果进行了解释。该方法导致的膜厚度的不确定性，但交换常数的温度变化的精确测定的交换常数的测定。
Resonance due to standing spin waves has been observed in thin films of Permalloy. The results are interpreted in terms of the Kittel spin pinning boundary condition and an ω vs k dispersion relation for good conductors. The method leads to a determination of the exchange constant subject to film thickness uncertainty but to a precise determination of the temperature variation of the exchange constant.
