    • Correlation between magnetic interactions and giant magnetoresistance in melt-spun co/sub 10/cu/sub 90/ granular alloys 

      Viegas, Alexandre da Cas; Geshev, Julian Penkov; Dorneles, Lucio Strazzabosco; Schmidt, Joao Edgar; Knobel, Marcelo (1997) [Artigo de periódico]
      The effects of annealing on the structural, magnetic, and magnetotransport properties of melt-spun Co10Cu90 granular alloys were investigated. The interaction effects were studied from both remanent magnetization and ...

    • Low potential barrier height effects in magnetic tunneling junctions 

      Cruz de Gracia, Evgeni Svenk; Dorneles, Lucio Strazzabosco; Schelp, Luiz Fernando; Teixeira, Sergio Ribeiro; Baibich, Mario Norberto (2007) [Artigo de periódico]
      This paper reports on the study of deposited (Ni81Fe19/AlOx /Co) magnetic tunnel junctions by magnetron sputtering, with the insulating layer obtained by plasma oxidation of Al. Concentration of the tunnel current in small ...

    • Magnetism in dilute magnetic oxide thin films based on SnO/sub 2/ 

      Fitzgerald, C.B.; Venkatesan, M.; Dorneles, Lucio Strazzabosco; Gunning, R.; Stamenov, Plamen; Coey, John Michael Douglas; Stampe, P.A.; Kennedy, R.J.; Moreira, Eduardo Ceretta; Sias, Uilson Schwantz (2006) [Artigo de periódico]
      Thin films of SnO2 prepared by pulsed-laser deposition on R-cut sapphire substrates exhibit ferromagnetic properties at room temperature when they are doped with Cr, Mn, Fe, Co, or Ni, but not with other 3d cations. ...

    • Observation of recoil magnetization curves outside the major loop in Co, Fe, and Ni films 

      Geshev, Julian Penkov; Garcia, Wagner Jesus da Silva; Paes, Vagner Zeizer Carvalho; Azeredo, Lucas Felipe Santos de; Dorneles, Lucio Strazzabosco; Andrade, Antonio Marcos Helgueira de (2021) [Artigo de periódico]
      We report a peculiar magnetization reversal observed in magnetron-sputtered Co, Fe, and Ni films. We found that some recoil (minor) magnetization curves lie entirely and way outside the major loop, a phenomenon referred ...

    • Tungsten oxide thin films grown by thermal evaporation with high resistance to leaching 

      Corrêa, Diogo da Silva; Pazinato, Julia Cristina Oliveira; Freitas, Mauricio Azevedo de; Dorneles, Lucio Strazzabosco; Radtke, Claudio; Garcia, Irene Teresinha Santos (2014) [Artigo de periódico]
      Óxidos de tungstênio apresentam diferentes estequiometrias, estruturas cristalinas e morfologias. Estas características são importantes principalmente quando se deseja utilizá-los como fotocatalisadores. Neste trabalho ...
