Phase diagram of imperfect ferromagnetic/antiferromagnetic-bilayers

PDF Version Also Available for Download.

Description

The phase diagram for ferromagnetic/antiferromagnetic bilayers with imperfect interfaces is calculated, using a Ising spin-1/2 model which is solved numerically in the mean field approximation for finite temperatures. We identify 3 stable phases: domains in the ferromagnet, domains in the antiferromagnet, and domain walls near the interfaces with homogeneous order within the layers. Phase transitions between these phases occur as a function of temperature, relative film thicknesses, and step density.
