    • Calculation of the temperature dependence of the giant mr and application to Co/Cu multilayers 

      Duvail, Jean-Luc; Fert, Albert R.; Pereira, Luis Gustavo; Lottis, Daniel Kurt (1994) [Artigo de periódico]
      Most theoretical models of the giant magnetoresistance (GMR) in metallic magnetic multilayers developed up to now are for the zero-temperature limit, thus neglecting the spin-flip scattering arising from spin fluctuations ...

    • Interplay between oscillatory exchange coupling and coercivities in giant magnetoresistive [Ni/sub 80/Fe/sub 20/Cu/Co/Cu] multilayers 

      Valet, Tierry; Jacquet, J.C.; Galtier, P.; Coutellier, J.M.; Pereira, Luis Gustavo; Morel, Robert; Lottis, Daniel Kurt; Fert, Albert R. (1992) [Artigo de periódico]
      We have observed giant magnetoresistance in [Ni80Fe20/Cu/Co/Cu] multilayers with well-defined oscillations in magnitude as a function of the Cu layer thickness both at 300 and 4.2 K. The phase and period are found to be ...

    • Magnetoresistance in rf-sputtered(nife/cu/co/cu) spin-valve multilayers 

      Lottis, Daniel Kurt; Fert, Albert R.; Morel, Robert; Pereira, Luis Gustavo; Jacquet, J.C.; Galtier, P.; Coutellier, J.M.; Valet, Tierry (1993) [Artigo de periódico]
      A study of the vtiation of the magnetoresistancein (Ni80Fe20/Cu/Co/Cu) multilayers with the thicknesses tNiFe, tcO, and &;cu of each type of component layer has been performed. The magnetoresistance (MR), which at 4 .2 K ...

    • Oscillatory interlayer exchange and magnetoresistance in Fe/Cu multilayers 

      Petroff, Frédéric; Barthelemy, Agnès; Mosca Junior, Dante Homero; Lottis, Daniel Kurt; Fert, Albert R.; Schroeder, Peter A.; Pratt Junior, W.P.; Loloee, Reza; Lequien, S. (1991) [Artigo de periódico]
      We have studied the magnetic and magnetotransport properties of Fe/Cu mu1tilayers prepared by sputtering. We find oscillations of the inter1ayer coupling as a function of the Cu thickness with the same long period as in ...

    • Treatment of the semiclassical Boltzmann equation for magnetic multilayers 

      Pereira, Luis Gustavo; Duvail, Jean-Luc; Lottis, Daniel Kurt (2000) [Artigo de periódico]
      We present an analytical treatment of the Camley–Barnas´ theory of the giant magnetoresistance ~GMR! in magnetic layered structures and obtain an exact and general expression for the resistivity. We used this expression ...
