Title :
Monte Carlo Simulation of Magnetotransport Properties in 
(FM) and 
C by some of these compounds. The essential ingredient of the CMR physics is not only the double-exchange interaction but also other competing interactions, such as ferromagnetic/antiferromagnetic superexchange interactions and charge/orbital ordering instabilities as well as their strong coupling with lattice distortion. In this work, a magnetotransport properties simulation of ferromagnetic (FM) La0.67Ca0.33MnO3 and antiferro magnetic (AF) La0.33Ca0.67MnO3 as a function of the temperature and the magnetic field is presented and discussed. Our study is addressed by using the Monte Carlo method on the basis of a Heisenberg model. Films thickness and external magnetic field influence on the resistivity and magnetoresistance (MR) was analyzed.
