A possible model to high TC ferromagnetism in Gallium Manganese Nitrides based on resonation properties of impurities in semiconductors

TL;DR

This paper explores the potential mechanisms behind high-temperature ferromagnetism in Gallium Manganese Nitrides, proposing a model based on impurity resonation properties and Bosonization, to explain experimental observations.

Contribution

It introduces a novel theoretical model linking impurity resonation and Bosonization to high TC ferromagnetism in (Ga,Mn)N, addressing discrepancies with existing theories.

Findings

High TC ferromagnetism observed in (Ga,Mn)N is similar to (Ga,Mn)As except for TC value

Proposes a model based on impurity resonation properties and Bosonization

Discusses the connection with Anderson localization problems

Abstract

The high TC ferromagnetism in (Ga,Mn)N were observed and almost all results are approximately similar to the experimental results in (Ga,Mn)As except the value of TC. Though all standard experiments on magnetism clearly support the results, the value is unexpectedly high. This work present and discuss the possibility of high TC ferromagnetism, after brief review of the experimental results. The key speculation to Bosonization method in three dimensions is resembled with the problems in Anderson localization.
