我们首次测量了 Cu/Co/Cu/Ni(Fe) 多层膜中热导率的场依赖性，该多层膜在低温下表现出 50% 的大磁阻。我们发现热导率与磁滞具有类似大小的大场依赖性，这表明导致巨磁阻的传导电子散射主要是大角度和弹性的，至少在低温下是这样。
We present the first measurement of the field dependence of thermal conductivity in Cu/Co/Cu/Ni(Fe) multilayer film which shows large magnetoresistance of 50% at low temperatures. We found a large field dependence of similar magnitude in thermal conductivity with hysteresis, which suggests that the conduction electron scattering responsible for the giant magnetoresistance is mostly large angle and elastic in nature, at least at low temperatures.
