Magnetization anisotropy of semiconductor quantum wires with magnetoelectric quantization

Abstract

The carrier magnetization of diluted magnetic semiconductor quantum wires having hybrid magnetoelectric quantization has been investigated. The magnetization as a function of the chemical potential shows that magnetic ions in semiconductor quantum wires enhance the magnetization and induce nonzero magnetization in a low-chemical-potential region. Magnetization anisotropy is not predominant in quantum wires while it is manifested in quantum wells because this anisotropy originates from changes in the density of states. The magnetization of quantum wires shows superimposed oscillations due to two hybrid eigenfrequencies.
