    • Spin texture on top of flux avalanches in Nb/Al2O3/Co thin film heterostructures 

      Lopes, Rovan Fernandes; Carmo, Danusa do; Colauto, Fabiano; Ortiz, Wilson Aires; Andrade, Antonio Marcos Helgueira de; Johansen, Tom Henning; Baggio-Saitovitch, E.; Pureur Neto, Paulo (2017) [Artigo de periódico]
      We report on magneto-optical imaging, magnetization, Hall effect, and magneto-resistance experiments in Nb/Al2O3/Co thin film heterostructures. The magneto-transport measurements were performed in samples where electrical ...

    • A study of the structural, magnetic, and electrical properties of Ba1-xNaxCoO3 compounds (x = 0.25, 0.5, 0.75) 

      Estrada-Rodríguez, Carlos A.; Lopes, Lutiene Fernandes; Lopes, Rovan Fernandes; Mesquita, Fabiano; Turatti, Águeda Maria; Pimentel Junior, Jorge Luiz; Sandoval-Gutiérrez, Santiago; Parra Vargas, Carlos Arturo (2021) [Artigo de periódico]
      Cobaltite-like materials having metal-insulator transitions are relevant in the consumer electronics market. In this work, we present the structural, magnetic, and electrical properties of Ba1-xNaxCoO3(with x= 0.25, 0.5, ...
