Abstract

The freezing of spins in the two‐dimensional ±J‐model [1,2] (anti‐ and ferromagnetic nearest neighbour bonds between Ising spins) is investigated for the case of a one‐spin‐flip‐dynamic (as used in Monte‐Carlo calculations). The phenomenon is caused by the existence of finite energy barriers between the different ground‐state valleys. The barrier heights are calculated by a numerical method ...
