Temperature effects on the magnetization of quasi-one-dimensional Peierls distorted materials

TL;DR

This paper investigates how temperature influences magnetization in Peierls distorted quasi-one-dimensional materials, revealing that temperature disrupts magnetization and that magnetization remains zero without an external magnetic field.

Contribution

The study provides a mean-field finite temperature phase diagram and explicitly calculates tricritical points for these materials, enhancing understanding of their magnetic behavior.

Findings

Temperature disrupts magnetization in Q1DM.

Magnetization remains zero without external magnetic field.

Temperature does not induce magnetization effects.

Abstract

It is shown that temperature acts to disrupt the magnetization of Peierls distorted quasi-one-dimensional materials (Q1DM). The mean-field finite temperature phase diagram for the field theory model employed is obtained by considering both homogeneous and inhomogeneous condensates. The tricritical points of the second order transition lines of the gap parameter and magnetization are explicitly calculated. It is also shown that in the absence of an external static magnetic field the magnetization is always zero, at any temperature. As expected, temperature does not induce any magnetization effect on Peierls distorted Q1DM.
