Abstract

We have fabricated pillar-like microstructures of high vacuum sputtered Fe/Cr magnetic multilayers and measured the giant magnetoresistance effect in the configuration where the measuring current is perpendicular to the film plane from 4.2 K to 300 K. At 4. 2 K we find a magnetoresistance of 108 % for multilayers with a Fe thickness of 3 nm and a Cr thickness of 1 nm. The pronounced temperature dependence of the perpendicular magnetoresistance is studied for samples with different Cr thicknesses and tentatively explained by electron-magnon scattering. The low-temperature data are compared with existing low-temperature models.
