    • Antiparallel interface coupling evidenced by negative rotatable anisotropy in IrMn/NiFe bilayers 

      Schäfer, Deise; Grande, Pedro Luis; Pereira, Luis Gustavo; Azevedo, Gustavo de Medeiros; Oliveira, Artur Harres de; Sousa, Marcos Antonio de; Pelegrini, Fernando; Geshev, Julian Penkov (2015) [Artigo de periódico]
      Negative rotatable anisotropy is estimated via ferromagnetic resonance measurements in as-made, annealed, and ion-irradiated IrMn3/Ni81Fe19 bilayers. Opposite to previous observations, inverse correlation between rotatable ...

    • 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 ...
