Abstract
Temperature dependence of the electrical resistivity has been measured below 50 K for the sputtered magnetic multilayers [Co(1.02 nm)/Cu(t Cunm)]25 with different Cu thickness at various magnetic fields. It is found that the electrical resistivities of ferromagnetic (FM) multilayer (tCu = 0.76 nm) and the antiferromagnetic (AFM) one (tCu = 1.05 nm) show temperature dependence of T3/2 and T2, respectively. The slope, A′, of each power law has a maximum near Hs. The results imply that the magnetic fluctuation is a maximum near Hs showing quantum phase transition.
