Title:
Symmetric Magnetization Reversal in Polycrystalline Exchange Coupled Systems via Simultaneous Processes of Coherent Rotation and Domain Nucleation 
Abstract:
Training in exchange bias systems plays an essential role in understanding the very origin of the biasing effect. The nonequilibrium arrangement of antiferromagnetic (AF) spins at the antiferromagnetic-ferromagnetic interface, related to the AF uniaxial anisotropy, plays a crucial role during the initial training. Our system of choice, IrMn/CoFe, possesses softer uniaxial anisotropy compared to other AF systems (e.g., CoO), thereby reducing the energy penalty due to nonequilibrium spins. Differe...    »
