Influence of the chemical surface structure on the nanoscale friction in plasma nitrided and post-oxidized ferrous alloy
Freislebem, Márcia; Menezes, Caren Machado; Bohn, Felipe; Costi, Fernanda Buratti; Ferreira, Patrícia A.; Aguzzoli, Cesar; Baumvol, Israel Jacob Rabin; Alvarez, Fernando; Figueroa, Carlos Alejandro (2014) [Artigo de periódico]Friction is a ubiquitous phenomenon in everyday activities spanning from vehicles where efficient brakes are mandatory up to mechanical devices where its minimum effects are pursued for energy efficiency issues. Recently, ... -
Magnetization dynamics in nanostructures with weak/strong anisotropy
Andrade, Antonio Marcos Helgueira de; Corrêa, Marcio Assolin; Viegas, Alexandre da Cas; Bohn, Felipe; Sommer, Rubem Luis (2014) [Artigo de periódico]We investigate the high-frequency response of magnetization dynamics through magnetoimpedance (MI) effect in Permalloy-based multilayered thin films produced with two different non-magnetic metallic spacers: Cu and Ag. Due ... -
Quantifying magnetic anisotropy dispersion : theoretical and experimental study of the magnetic properties of anisotropic FeCuNbSiB ferromagnetic films
Alves, Tibério Magno de Lima; Bezerra, Claudionor Gomes; Viegas, Alexandre da Cas; Nicolodi, Sabrina; Corrêa, Marcio Assolin; Bohn, Felipe (2015) [Artigo de periódico]We performed a theoretical and experimental investigation of the quasi-static magnetic properties of anisotropic systems. We considered a modified Stoner-Wohlfarth model to describe anisotropic systems, and a distribution ... -
Tunable asymmetric magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films
Silva, Edimilson Felix da; Gamino, Matheus; Andrade, Antonio Marcos Helgueira de; Corrêa, Marcio Assolin; Vázquez Villalabeitia, Manuel; Bohn, Felipe (2014) [Artigo de periódico]We investigate the magnetization dynamics through the magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films. We observe that the magnetoimpedance response is dependent on the thickness of the non-magnetic Cu spacer ...
