MICROMAGNETISM INDUCED BY THE UNPAIRED ELECTRONS IN InSb SINGLE CRYSTAL

Abstract

In this paper, our experimental results demonstrate that the micromagnetism of InSb is determined by J (where J = L+S) instead of S of unpaired electrons due to the strong spin–orbit coupling. The results of macromagnetism show that the magnetism is diamagnetic, which comes from the Lamor moment of localized electrons and Landau diamagnetic moment of conduction electrons. Below 160 K, ferromagnetic ordering of J, which is induced by the interaction between J, also promotes the appearance of metallic behavior which is different from the well-known band theory.
