Abstract

We have synthesized polycrystalline indium antimonide samples codoped with Mn (1 at %) and Ni (0.8, 1, or 1.2 at %). The magnetic properties of these materials have been shown to be dominated by Ni_{2 –}_хMnSb (0 < х < 1) clusters, whose composition and Curie temperature depend on Ni content. The samples exhibit metallic behavior of conductivity and have a positive magnetoresistance below room temperature.
