— This paper presents an analytical review that addresses physicochemical principles underlying the synthesis of granular structures in semiconductor–ferromagnet systems. Such systems comprise a II–IV–V2, II2–V3, or II–V2 compound as a semiconductor and MnAs as a ferromagnet. We demonstrate that granular magnetic structures are an alternative to superlattices in spintronic devices and can exhibit...
— 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 Ni2 –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...
