Abstract

The pressure dependences of electrical resistance, Hall coefficient, charge carrier mobilities, and magnetoresistance of the Cd₃As₂–20 mol % MnAs composite are investigated at pressures up to 9 GPa. The pressure dependences of all the listed properties exhibit features related to phase transitions. The presence of pressure-induced negative magnetoresistance is registered.

高压下Cd 3 As 2 – 20 mol％MnAs复合材料的电和电磁性能

摘要

在高达9 GPa的压力下研究了Cd ₃ As _{2 –} 20 mol％MnAs复合材料的电阻，霍尔系数，电荷载流子迁移率和磁阻的压力依赖性。所有列出的特性的压力依赖性都表现出与相变有关的特征。记录了压力引起的负磁阻的存在。
