Modified scaling relation for the random-field Ising model

Nowak, U.; Usadel, K.D.; Esser, J. - In: Physica A: Statistical Mechanics and its Applications 250 (1998) 1, pp. 1-7

We investigate the low-temperature critical behavior of the three-dimensional random-field Ising ferromagnet. By a scaling analysis we find that in the limit of temperature T→0 the usual scaling relations have to be modified as far as the exponent α of the specific heat is concerned. At zero...

Dynamics of domains in diluted antiferromagnets

Nowak, U.; Esser, J.; Usadel, K.D. - In: Physica A: Statistical Mechanics and its Applications 232 (1996) 1, pp. 40-50

We investigate the dynamics of two-dimensional site-diluted Ising antiferromagnets. In an external magnetic field these highly disordered magnetic systems have a domain structure which consists of fractal domains with sizes on a broad range length scales. We focus on the dynamics of these...
