摘要：

In the present investigation, we evaluated the half-metallic-ferromagnetic/antiferromagnetic nature of Fe/Co/Ni doped ZnSe material systems. Our calculations show that for the majority spin channel, Zn0.75Fe0.25Se, Zn0.75Co0.25Se, and Zn0.75Ni0.25Se, are semiconductors, and for the minority spin channel, they are conductors and hence are predicted to be half-metallic ferromagnetic/antiferromagnetic in nature. Furthermore Zn0.75Fe0.25Se and Zn0.75Ni0.25Se are ferromagnetic and Zn0.75Co0.25Se is antiferromagnetic. The structural, electronic, and magnetic properties of these materials are also calculated and discussed in detail. (C) 2009 American Institute of Physics. [doi: 10.1063/1.3256186]
