本文报道了四元Heusler合金CoFeCrAl的磁体积效应,它是一种潜在的自旋无带隙半导体材料。CoFeCrAl的晶体结构被确认为有序LiMgPdSn型结构的单相。从在环境压力下的磁化强度测量,居里温度和自发磁化强度被确定为575.2 K和2.01/f. u.,分别该温度比室温高得多,遵循斯莱特-鲍林规则。高压磁化强度测量表明,CoFeCrAl的电子态在10 K和300 K之间几乎不受压力的影响,表明CoFeCrAl的电子态是完全自旋极化的,并且在300 K时仍保持不变。实验结果表明,四元Heusler合金CoFeCrAl是一种很有吸引力的自旋电子学器件功能电极铁磁体材料。
We report the magnetovolume effect of quaternary Heusler alloy CoFeCrAl as a potential candidate of spin gapless semiconductor. The crystal structure of CoFeCrAl was confirmed as the single phase of the ordered LiMgPdSn-type structure. From magnetization measurements at ambient pressure, the Curie temperatureand the spontaneous magnetizationwere determined to be 575.2 K and 2.01/f.u., respectively. Theis higher enough than room temperature and thefollows the Slater–Pauling rule. High-pressure magnetization measurements showed that theis almost independent of applying pressures not only at 10 K but also up to 300 K, exhibiting that the electronic state of CoFeCrAl is fully spin polarized and it is preserved even at 300 K. The experimental results reveal that the quaternary Heusler alloy CoFeCrAl is an attractive material for functional electrode ferromagnets in spintronics devices.
