测量了Cr75FexMn25-x(x=16,18)合金的热导和电导,温度范围为77—300K.在SDW反铁磁转变附近观察到热导率温度曲线斜率的改变和电导率极大,这与反铁磁转变过程中能隙的打开有关.对合金低温热导率结果的分析处理指出,在声子热导中起作用的主要是声子散射的U过程
The thermal and electrical conductivities of Cr75FexMn25-x (x = 16,18) alloys were measured at 77-300K. In the vicinity of the SDW antiferromagnetic transition, a change in the slope of the thermal conductivity-temperature curve and an extremely large conductivity were observed, which was related to the opening of the energy gap during the antiferromagnetic transition. Analysis of the results of low temperature thermal conductivity of the alloy points out that the phonon scattering U-process
