Nanocomposites containing soft and hard magnetic phases have attracted immense attention for energy-related and biomedical applications. With exchange coupling between nanoscale grains in the composites, magnetization of the soft magnetic phase can rotate coherently with that of the hard magnetic phase. In particular, good control of the soft and hard phases at the nanoscale in the composites i...

The exchange bias in antiferromagnet (MnF2)/ferromagnet ~Fe! bilayers has been studied as a function of temperature, cooling field, and interfacial roughness. Positive exchange bias is observed under certain conditions, along with a nonmonotonic roughness dependence. The unusual cooling field dependence can be understood within a simple model in which the exchange bias is determined by a compet...
