摘要：

We have studied the magnetic properties of In1 − xMnxSb substitutional solid solutions. The results indicate that, at Mn contents below 0.5 at %, the materials contain microinclusions close in composition to the ferrimagnetic compound Mn2Sb, which has a layered structure with magnetically active manganese in two structurally inequivalent sites, Mn1 and Mn2. Zinc doping of Mn2Sb breaks up one of its magnetic sub-lattices and converts the ferrimagnet to a ferromagnet. This property is basic to the proposed ferromagnetic semiconductor based on InSb codoped with Mn and Zn, which has a Curie temperature near 320 K.
