    • Interdependence between training and magnetization reversal in granular Co-CoO exchange bias systems 

      Menéndez Dalmau, Enric; Dias, Thiago; Geshev, Julian Penkov; López-Barberá Martín, José Francisco; Nogués Sanmiquel, Josep; Steitz, Roland; Kirby, Brian J.; Borchers, Julie A.; Pereira, Lino Miguel da Costa; Vantomme, A.; Temst, Kristiaan (2014) [Artigo de periódico]
      The interdependence between training and magnetization reversal in granular Co-CoO exchange bias (EB) systems prepared byOion implantation inCo thin films is demonstrated by polarized neutron reflectometry. While high-fluence ...

    • Rotatable anisotropy driven training effects in exchange biased Co/CoO films 

      Dias, Thiago; Menéndez Dalmau, Enric; Liu, Haoliang; Van Haesendonck, Christian; Vantomme, A.; Temst, Kristiaan; Schmidt, Joao Edgar; Giulian, Raquel; Geshev, Julian Penkov (2014) [Artigo de periódico]
      The training effect for exchange bias in field-cooled Co/CoO bilayers films is investigated. Previous experiments on the same system have shown that, starting from the ascending branch of the first hysteresis loop, coherent ...

    • Tuning the ferromagnetic-antiferromagnetic interfaces of granular Co-CoO exchange bias systems by annealing 

      Menéndez Dalmau, Enric; Modarresi, Hiwa; Dias, Thiago; Geshev, Julian Penkov; Pereira, Lino Miguel da Costa; Temst, Kristiaan; Vantomme, A. (2014) [Artigo de periódico]
      The low-temperature magnetic behavior of granular Co-CoO exchange bias systems, prepared by oxygen ion implantation in Co thin films and subsequent annealing, is addressed. The thermal activation effects lead to an O ...
