Abstract

In this study, a model for obtaining the AC magnetic susceptibility of La2/3Ca1/3MnO3 manganites was proposed. The samples were composed of a combination of Mn4+ and Mn3+ ions that influence the material stoichiometry. The model is based on the Hamiltonian, including the Heisenberg interaction and the Zeeman effect. For determining AC susceptibility, a time-dependent external magnetic field h(t) was applied to the sample. Several mathematical tools, such as Fourier transforms, were required for performing the simulations. The study was conducted for various angular frequencies and temperatures. The simulations were obtained using a graphic interface that allowed the online monitoring of the results. According to the results, the AC susceptibility decreases not only with the temperature, but also with the frequency
