We use a method which employs a dynamic calculation of magnetization motion to find both the static configuration and the spin wave excitations in a ferromagnet/antiferromagnet layered structure. Our results for the static structure are similar to th

We investigate the properties of the dynamic permeability for a layered structure composed of a ferromagnet with low anisotropy coupled to a ferromagnet with high anisotropy. The permeability of a structure with a small number of layers (200) can be

Microwave propagation in a layered dielectric/ferromagnet were explored in the past. Previous studies, however, made use of an approximation to the full permeability tensor in the ferromagnet. This approximation fails in a frequency range where the s

A thin ferromagnetic film coupled to an antiferromagnet can exhibit exchange biasing where the hysteresis curve is shifted slightly. A explanation for this shift has been proposed recently by Koon where it was argued that a surface spin flop state in

Using Monte Carlo simulations and analytic methods, we study the effects of competition and mutation between species with age structure. For definiteness, simulations are based on the reproductive and age structures of the Penna-Desai model. In gener

A century ago, the foundations of equilibrium statistical mechanics were laid. For a system in equilibrium with a thermal bath, much is understood through the Boltzmann factor, exp{-H[C]/kT}, for the probability of finding the system in any microscop
