Frustration Driven Stripe Domain Formation in Co/Pt Multilayer Films

Davies, J.E., O. Hellwig, E. E. Fullerton, M. Winklhofer, R. D. Shull, and Kai Liu (2009), Frustration Driven Stripe Domain Formation in Co/Pt Multilayer Films, Appl. Phys. Lett., 95, 022505, doi:10.1063/1.3179553.

Abstract
We report microscopic mechanisms for an unusual magnetization reversal behavior in
Co/Pt multilayers where some of the first-order reversal curves protrude outside of the major
loop. Transmission x-ray microscopy reveals a fragmented stripe domain topography when the
magnetic field is reversed prior to saturation, in contrast to an interconnected pattern when
reversing from a saturated state. The different domain nucleation and propagation behaviors are
due to unannihilated domains from the prior field sweep. These residual domains contribute to
random dipole fields that impede the subsequent domain growth and prevent domains from
growing as closely together as for the interconnected pattern.
