Comment on the possibility of Inverse Crystallization within van Hemmen's Classical Spin-Glass model

TL;DR

This paper discusses how van Hemmen's classical spin-glass model can be extended to explain inverse crystallization phenomena by incorporating the temperature dependence of RKKY interactions, potentially impacting other models.

Contribution

It introduces a generalization of van Hemmen's model to include temperature-dependent RKKY interactions, explaining inverse crystallization.

Findings

The model can account for ferromagnetic phases at higher temperatures.

Temperature dependence of RKKY interactions is crucial.

Potential applicability to other spin-glass models.

Abstract

In this comment, I show that van Hemmen's classical spin-glass model can also account for processes such as inverse crystallization, where a ferromagnetic phase appears at higher temperatures than a glass state. The so far ignored fact is the temperature dependence of the Ruderman-Kittel-Kasuya-Yosida interaction. This generalization may be relevant to other models.
