Abstract
The exchange biaseffect in ferromagnetic/antiferromagnetic sandwich structures is generally believed to be sensitive on the interfaceexchange interaction, the magnetization, and the thickness of the ferromagnetic layer. Also the interface structure plays a crucial role. We show that, by irradiating samples with He ions, we can manipulate the exchange bias field in a controlled manner. Depending on the dose (1014-1017 ions/cm2) and the acceleration voltage (10-35 kV) of the ions, the shift of the hysteresis can be reduced or even fully suppressed. Potential applications of this effect for magnetic patterning on the nanoscale will be discussed.
