Nontrivial critical behavior of the free energy in the two-dimensional Ising spin glass with bimodal interactions
Helmut G. Katzgraber, L. W. Lee, I. A. Campbell
A detailed analysis of Monte Carlo data on the two-dimensional Ising spin glass with bimodal interactions shows that the free energy of the model has a nontrivial scaling. In parti…
Dynamic critical behaviour in Ising spin glasses
Michel Pleimling, I. A. Campbell
The critical dynamics of Ising spin glasses with Bimodal, Gaussian, and Laplacian interaction distributions are studied numerically in dimensions 3 and 4. The data demonstrate that…
Ordering temperatures of Ising Spin Glasses
I. A. Campbell
Exploiting an approach due to Singh and Fisher I show that in the high dimension limit the ordering temperature of near neighbour Ising Spin Glasses drops linearly with the kurtosi…
Dynamical scaling in Ising and vector spin glasses
Helmut G. Katzgraber, I. A. Campbell
We have studied numerically the dynamics of spin glasses with Ising and XY symmetry (gauge glass) in space dimensions 2, 3, and 4. The nonequilibrium spin-glass susceptibility and…
The Anomalous Hall effect in re-entrant AuFe alloys and the real space Berry phase
P. Pureur, F. Wolff Fabris, J. Schaf +2
The Hall effect has been studied in a series of AuFe samples in the re-entrant concentration range, as well as in the spin glass range. The data demonstrate that the degree of cant…
