Comment on the paper 'Thermodynamics of two-dimensional magneto nanoparticles' by P. Vargas, D. Altbir, M. Knobel and D. Laroze

TL;DR

This paper critiques a previous study on two-dimensional magnetic nanoparticles, demonstrating that the claimed bi-stability does not exist in the system analyzed.

Contribution

It provides a critical analysis showing the absence of bi-stability in the model studied by Vargas et al., clarifying the system's thermodynamic behavior.

Findings

No bi-stability in the considered nanoparticle system

Reassessment of previous thermodynamic claims

Clarification of system stability properties

Abstract

It is shown that there is no bi-stability in the system of two-dimensional nanoparticles considered by P. Vargas et al.
