Abstract
Using direct melting and quenching of InSb + 0.058-0.23 wt % Mn + 1.1 wt % Zn, we have prepared polycrystalline InSb〈Mn, Zn〉 solid solutions containing much less impurity phases in comparison with earlier studied InSb〈Mn〉 substitutional solid solutions containing manganese on the indium site. As shown by electron probe x-ray microanalysis and electrical and magnetic measurements, the synthesized solid solutions consist of InSb〈Mn〉 substitutional solutions and InSb〈Zn〉 interstitial solutions. The room-temperature hole concentration and magnetization of InSb〈Mn, Zn〉 p exceed those of InSb〈Mn〉. The electrical and magnetic properties of the magnetic material InSb〈Mn, Zn〉 fit well with indirect kinematic ferromagnetic exchange theory.
