Magnetic properties of the spin-1/2 transverse ferromagnetic bilayer system with disordered interfaces

Abstract

The effects of an applied transverse magnetic field on the magnetic properties in a ferromagnetic bilayer system with disordered interfaces consisting of spin-1/2 atoms are investigated using the effective field theory. The magnetization protiles and the phase diagrams. namcl, T-c versus the concentration p, T-c versus the interlayer exchange interaction and T-c versus the transverse field plots are discussed. It is shown that the existence of the disordered interfaces may severely affect the phase diagrams of T-c When the transverse field is applied and the interlayer exchange interaction is selected as the large value. some characteristic effects due to them can be obtained in the critical properties of the system. such as the reentrant phenomenon observed for special cases.
