Abstract
The paper deals with the study of coexisting majority and minority components in thin ferromagnetic film which is magnetically stripped by applying external magnetic field in selected regions. There occurs continuous transition from ferromagnetic barriers to a coexisting phase separated region through the formation of a depletion layer. Formation of magnetic barriers, channels and step like structure have been explored. Temperature induced two regime behavior is observed – first one dominated by the ferroic nature of the film and the second one by the paramagnetic nature of film. Two sizes of lattice in 3 dimensions of 100 × 100 × 100 and 200 × 100 × 100 are used for Monte Carlo simulation using Ising model with Metropolis algorithm. The spin polarization, average magnetization and spin correlation functions are plotted to reveal the underlying physics. The micrographs of the magnetic barrier and phase separated regions are also shown.
