Abstract

The stability of the exchange bias field 𝐻eb has been studied for magnetron sputtered NiO/Ni66Co18Fe16 and Ni66Co18Fe16/FeMn bilayers. A forced antiparallel alignment of the ferromagnetic magnetization to 𝐻eb results in a gradual decrease of 𝐻eb as a function of time for NiO as well as FeMn based samples. The observed decrease of 𝐻eb increases with temperature and is interpreted as a thermally assisted reversal of magnetic domains in the antiferromagnetic layer.
