Monte Carlo simulation with time step quantification in terms of Langevin dynamics
U. Nowak, R. W. Chantrell, E. C. Kennedy
For the description of thermally activated dynamics in systems of classical magnetic moments numerical methods are desirable. We consider a simple model for isolated magnetic parti…

Field dependence of the temperature at the peak of the ZFC magnetization
H. Kachkachi, W. T. Coffey, D. S. F. Crothers +4
The effect of an applied magnetic field on the temperature at the maximum of the ZFC magnetization, , is studied using the recently obtained analytic results of Coffey et…

Thermally activated escape rates of uniaxial spin systems with transverse field
D. A. Garanin, E. C. Kennedy, D. S. F. Crothers +1
Classical escape rates of uniaxial spin systems are characterized by a prefactor differing from and much smaller than that of the particle problem, since the maximum of the spin en…
