    • Bias dependence of magnetoresistance in Fe-Al/sub 2/O/sub 3/ granular thin films 

      Boff, Marco Aurelio Silveira; Geshev, Julian Penkov; Schmidt, Joao Edgar; Flores, Wladimir Hernandez; Antunes, Arlei Borba; Gusmao, Miguel Angelo Cavalheiro; Teixeira, Sergio Ribeiro (2002) [Artigo de periódico]
      This paper reports on the magnetotransport behavior of Fe–Al2O3 granular thin films when the injected dc current is varied. The electric resistance as a function of temperature, magnetoresistance, and the current vs applied ...

    • Change of the electrical properties in Fe-Al/sub 2/O/sub 3/ granular films 

      Boff, Marco Aurelio Silveira; Teixeira, Sergio Ribeiro; Schmidt, Joao Edgar; Antunes, Arlei Borba (2004) [Artigo de periódico]
      A systematic study of the electrical resistance as a function of the temperature was performed in Fe-Al2O3 granular thin films. Our findings revealed a nonlinear dependence of the current versus voltage in the low field ...

    • Development of granular structure in Cu/sub 90/Co/sub 10/ ribbons through furnace and current annealing 

      Silva, F.C.S.; Knobel, Marcelo; Ferrari, Edson Fernando; Denardin, Juliano C.; Miranda, Marines Grande Malcum; Bracho Rodriguez, Gustavo Jesus; Antunes, Arlei Borba; Baibich, Mario Norberto (2000) [Artigo de periódico]
      On-line measurements of resistance and temperature in melt-spun Cu90Co10 ribbons are made using two different annealing techniques: conventional furnace annealing, and linearly varying current Joule heating. The aim of ...
