COEXISTENCE OF BUBBLES AND STRIPE DOMAINS IN THIN MAGNETIC FILMS WITH PERPENDICULAR ANISOTROPY

Abstract

The possibility of coexistence of a magnetic bubble lattice (MBL) and a stripe domain structure (SDS) as two domain phases of a thin magnetic film at various temperatures has been studied from the point of view of the balance their magnetostatic pressures. It is shown that such two-phase structures respond to increasing the film temperature by the phase boundary advance from the MBL to the SDS. This advance is a reversible one until the temperature of the phase transition in the MBL phase.
