The Monte Carlo Antiferromagnetic Ising model was used to study the electrical properties and magnetoresistance of manganese oxides due to the charge ordering phase occurring at half doping, _x = 0.5_. The half-doped manganites have an insulator antiferromagnetic ground state. The internal energy, specific heat, resistivity, the magneto-resistance and magnetization have been investigated with different applied magnetic fields. Our simulation ... Read more
