We present MagAnalyst, a user-friendlyMatlab toolbox that simplifies the fitting process of anhystereticmagnetization curves using the Langevin-Weiss equation of state. This toolboxfollows the framework proposed by Silveyra and Conde Garrido, allowing for thecharacterization of anisotropic materials using a negative Weiss´ molecularfield constant and the characterization of inhomogeneous materials throughmulticomponent magnetizations. Our work demonstrates that MagAnalyst canprovide reliable and accurate solutions, while also enabling the retrieval ofimportant quantities such as the anisotropy mean field and the inducedanisotropy energy constant. By freely distributing this toolbox (https://github.com/matias-gonz/maganalyst/),we aim to offer a valuable resource for studying and understanding the magneticproperties of soft magnets, ultimately contributing to the development ofadvanced magnetic devices.
