Training-induced positive exchange bias in NiFe/IrMn bilayers.

Abstract

Positive exchange bias has been observed in the Ni81Fe19/Ir20Mn80 bilayer system via soft-x-ray resonant magnetic scattering. After field cooling of the system through the blocking temperature of the antiferromagnet, an initial conventional negative exchange bias is removed after training, i.e., successive magnetization reversals, resulting in a positive… (More)
