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