摘要
Spintronic applications rely on ferromagnetic/antiferromagnetic exchange biased bilayers. In this study, we show whether and how disordered magnetic phases, which exhibit low freezing temperatures and are located in the ferromagnetic/antiferromagnetic thin film, affect the device-to-device variability of exchange bias in magnetic applications once the film is nanofabricated.
