Pb. Zhao et al., INTERPRETATION OF THE GIANT MAGNETORESISTANCE OSCILLATION WITH THE THICKNESS OF FERROMAGNETIC LAYER IN MAGNETIC MULTILAYERS, Chinese Physics Letters, 12(8), 1995, pp. 485-488
In virtue of Mott mechanism, we calculate the giant magnetoresistance(
GMR) in Pe/Cr superlattices. Our results show that the GMR oscillation
s with the thickness of the ferromagnetic layer is due to the finite s
ize effect of magnetic itinerant holes. The calculation is consistent
with the experimental observation.
