Ferrimagnetos de Ising con Diluci\'on

TL;DR

This study numerically investigates a 3D Ising mixed model with non-magnetic impurities, revealing how impurity concentration affects critical and compensation temperatures, with implications for magnetic phase transitions.

Contribution

It provides new insights into how quenched non-magnetic impurities influence phase transition temperatures in a 3D Ising model.

Findings

Compensation and transition temperatures decrease linearly with impurity concentration below 30%.

Above 30% impurities, the compensation temperature vanishes.

Impurities significantly alter magnetic phase transition behavior.

Abstract

We perform numerical studies of a three dimensional Ising mixed model at different concentrations of quenched non magnetic impurities. Our preliminary results indicate that both, the compensation temperature and the temperature that signal the transition from an ordered to a disordered phase, decrease linearly with the concentration of impurities, for concentrations below 30%. For percentages of impurities above 30% the compensation temperature disappears.
