Hysteresis reduction in NiFeCo/Cu multilayers exhibiting large low-field giant magnetoresistance
Giant magnetoresistance (GMR) has been observed in Ni66Fe16Co18/Cu multilayered uniaxial magnetic thin films prepared by dc magnetron sputtering. Both easy and hard axis loops saturate at very low app...

Magnetization reversal in CoFe/Ag/Fe/ZnSe thin layer sandwiches
In recent work [J. Appl. Phys. 70, 10 (1991)] the spin valve effect (SVE) was measured in CoxFe1−x/Ag/Fe(x<0.7) thin layer sandwiches grown by molecular beam epitaxy. The field dependence of ...

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 (magnons), as well as other scatterings from thermal excitations. To account for the temperature dependence of the GMR, we have introduced electron–magnon and electron–phonon scattering terms in a Camley–Barnas-like semi-classical model. We apply our calculation to the interpretation of the temperature dependence of the resistivity and GMR in Co/Cu. Journal of Applied Physics is copyrighted by The American Institute of Physics.

  9. The angular integration is stopped at an angle corresponding to cos ThetaC = 1/sqrt(k[sub f][sup *] lambda ) before the direction parallel to the layer plane, which can be justified by arguing that if the electron lifetime is finite, the uncertainty principle prevents its velocity from being exactly parallel to the layers.
