Abstract

Using Ising model Monte Carlo simulations, we show a strong dependence of surface magnetization on surface miscut angle. For ferromagnetic surfaces, when surface spin exchange coupling is larger than that of the bulk, the surface magnetic ordering temperature decreases, toward the bulk Curie temperature, with increasing miscut angle; when surface spin exchange coupling is smaller than that of the bulk, a crossover behavior occurs: at low temperature, the surface magnetization decreases with increasing miscut angle; at high temperature, the reverse is true.

16. In deriving eqn. (2), the interaction between a surface spin and bulk spin is calculated as the geometric average of those betweentwo surface spins and two bulk spins, as we did in the actual simulations. We have tested that the crossover will also appear at the extreme case when the interaction between a surface spin and a bulk spin is treated as equal to that between two bulk spins.Google Scholar
