AB The usefulness of modeling magnetocaloric materials expands from the understanding oftheir behavior to the prediction of new materials, playing a fundamental role in the opti-mization of their performance. In contrast with other areas of magnetic materials research,micromagnetic simulations of magnetocaloric materials are scarce due to the difficultyof modeling the material in the vicinity of the transition. To solve this limitation, wepropose to use the Landau–Lifshitz–Bloch micromagnetic simulations to study the mag-netocaloric effect associated with a second-order ferromagnetic↔paramagnetic transition.Following our proposed methodology and considering material parameters in a mean-fieldframework, we obtain reliable isothermal entropy change curves for monocrystalline andpolycrystalline configurations, where we consider different anisotropic contributions. Therobustness of the method was evaluated, yielding results that agreed with previous ex-perimental and theoretical observations. Our study shows that micromagnetic simulationsare a powerful tool for analyzing second-order magnetocaloric materials with complexmicrostructures.
