Abstract

In this paper, we have studied the character of the resistivity curve through the spin Ising model containing the competition of ferromagnetic and antiferromagnetic interactions by using the mean-field analytic method for nearest-neighbor interactions. The results show that the plateaus emerge in the resistivity curve, and they have relatively significant similarities between the theoretical research and experiments of perovskite manganite Pr0.5Ca0.5Mn0.97Ga0.03O3. Moreover, show that the properties of these plateaus as the number, position, and height significantly depend on the model's parameters: the number of nearest-neighbor interactions z, the probability p, and the fluctuation .
