论文摘要
磁性和传输性能在当前的垂直平面到平面（CPP）旋转剂中探索，掺杂的宽带间隙半导体znte是铁电磁电极之一。在低温下，在这些CPP旋转阀中观察到了负磁力，温度依赖性很强。由于DFT计算所揭示的两种材料的自旋极化，因此可以通过（Zn，Cr）TE和钴（Zn，Cr）TE和钴在（Zn，Cr）TE和钴（Zn，Cr）TE和钴中的较大差异不对称系数的巨大差异来解释这种效果。
Magnetic and transport properties are explored in the current perpendicular-to-plane (CPP) spin salves with Cr doped wide band gap semiconductor ZnTe as one of the ferromagnetic electrodes. A negative magnetoresistance is observed in these CPP spin valves at low temperature, with a strong temperature dependence. This effect can be explained by the large difference of spin scattering asymmetry coefficients in (Zn,Cr)Te and Cobalt, due to the very different spin polarizations of the two materials as revealed by the DFT calculation.
