Spin-polarized transport and the electronic structure of the metallic antiferromagnet Fe(thiazole)(2)Cl(2).
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.
