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 ... -
Frequency-dependent exchange bias in NiFe/NiO films
Geshev, Julian Penkov; Pereira, Luis Gustavo; Schmidt, Joao Edgar; Nagamine, Luiz Carlos Camargo Miranda; Baggio-Saitovitch, E.; Pelegrini, Fernando (2003) [Artigo de periódico]Ferromagnetic (FM) resonance and magnetization curve measurements were performed at room temperature for a polycrystalline Ni81Fe19 coupled to NiO. It was observed that the shape of the angular variation of the resonance ...
