从理论上研究了Fe（噻唑）(2)Cl(2)纳米晶体的电子态密度、能带结构、自旋极化、自旋滤波效应和电流-电压曲线。结果表明，Fe（噻唑）(2)Cl(2)是具有半金属铁磁亚稳态的金属反铁磁体。铁磁亚稳态的自旋电流表明，Fe（噻唑）(2)Cl(2)具有自旋过滤特性。此外，由于Fe（噻唑）(2)Cl(2)的态密度窄，电流-电压曲线呈现负差分电阻。得到了理想的负磁阻。
We theoretically investigate the electron density of states, band structure, spin polarization, spin filter effect, and current-voltage curve of Fe(thiazole)(2)Cl(2) nanocrystal. The results show that Fe(thiazole)(2)Cl(2) is a metallic antiferromagnet with half-metallic ferromagnetic metastable state. The spin current for the ferromagnetic metastable state shows that Fe(thiazole)(2)Cl(2) has spin-filter property. Moreover, the current-voltage curve exhibits negative differential resistance, which is due to the narrow feature in the density of states of Fe(thiazole)(2)Cl(2). The perfect negative magnetoresistance is also obtained.
