Modelling compensated antiferromagnetic interfaces with MuMax³

We show how compensated antiferromagnetic interfaces can be implemented in the micromagnetic simulation program MuMax³. We demonstrate that we can model spin flop coupling as a uniaxial anisotropy for small canting angles and how we can take into account the exact energy terms for strong coupling between a ferromagnet and a compensated antiferromagnet. We also investigate athermal training in biaxial antiferromagnets and reproduce the training effect in a polycrystalline IrMn/CoFe bilayer. (paper)
