    • Effects of Ca and Sr chemical doping on the average superconducting kinetic energy of YBa2Cu3O7-δ 

      Vieira, Valdemar das Neves; Mendonça, A.P.A.; Dias, Fabio Teixeira; Hneda, Marlon Luiz; Pureur Neto, Paulo; Schaf, Jacob; Mesquita, Fabiano (2015) [Artigo de periódico]
      In this brief communication we applied the MZFC(T) and MFCC(T) reversible dc magnetizations to get the average superconducting kinetic energy density, kS(T,B) of YBa2Cu3O7-d, Y0.95Ca0.05Ba2Cu3O7-d and YBa1.75Sr0.25Cu3O7-d ...

    • Electrical magnetotransport properties in RCo12B6 compounds (R = Y, Gd, and Ho) 

      Mesquita, Fabiano; Magalhaes, Sergio Garcia; Pureur Neto, Paulo; Diop, Léopold Vincent Birane; Isnard, Olivier (2020) [Artigo de periódico]
      Remarkable electronic transport and magnetotransport properties are found in the intermetallic compounds RCo12B6 (R=Y, Ho, and Gd). Detailed resistivity, magnetoresistance, and Hall effect measurements are reported in the ...

    • Non-ohmic behavior of metal-insulator granular thin films in low-field regime (eDV kBT) 

      Boff, Marco Aurelio Silveira; Canto, B.; Mesquita, Fabiano; Hinrichs, Ruth; Fraga, Gilberto Luiz Ferreira; Pereira, Luis Gustavo (2016) [Artigo de periódico]
      Non-ohmic behavior is not expected in metal–insulator granular systems in a low-field regime. There is no model to explain this behavior, even though it has been reported in several metalinsulator granular thin films ...

    • 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, ...

    • Turn on of new electronic paths in Fe-SiO2 granular thin film 

      Boff, Marco Aurelio Silveira; Hinrichs, Ruth; Canto, B.; Mesquita, Fabiano; Baptista, Daniel Lorscheitter; Fraga, Gilberto Luiz Ferreira (2014) [Artigo de periódico]
      The electrical properties of Fe-SiO2 have been studied in the low-field regime (eDV kBT), varying the injected current and the bias potential. Superparamagnetism and a resistance drop of 4400X (for a voltage variation of ...
