In this work, magnetic and magnetotransport properties of ferromagnetic (FM)/antiferromagnetic (AF) (La2/3Ca1/3MnO3/La1/3Ca2/3MnO3)n (n = 1, 3, 5, 8) manganite multilayers using the standard Monte Carlo method were studied. Simulations of a three-dimensional classical Heisenberg model implemented with a single spin- flip Metropolis dynamics were performed. The Hamiltonian included four different superexchange interactions, accord- ing with the two different types of ions Mn 3+ and Mn 4+ . Also, the orbital differences accounting for the Mn 3+ ions were considered. Likewise, the Hamiltonian included terms dealing with magnetocrystalline anisotropy and the influ- ence of an external magnetic field. Samples were simulated with dimensions L 2 (dFM + dAF) ,w hereL stands for the lateral dimension along which periodic boundary condi- tions were implemented and d FM and dAF stand for the thicknesses of FM and AF layers, respectively, with free boundary conditions. In particular, low-temperature results reveal the behavior of the magnetoresistance depending of the thickness and the number of bilayers.
