The crystal-Geld effect o/spin-| transverse Ising model is studied with the scheme of mean-field approximation. The influences of the crystal field and the transverse field on the phase diagram of the system are discussed.
Based on a macroscopic theory in which the spin-dependent interface scattering and the bulk scattering are included, the transport properties in systems of cylindrical magnetic granules are investigated analytically. It is shown that the giant magnetoresistance as well as the resistivities of these systems depend strongly on the size of the granules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
