Abstract

We report Giant Magnetoresistance (GMR) in Co/Cu multilayers deposited using high vacuum electron beam evaporation on Si(111) and Si(100). Samples grown on Si(111) show enhanced magnetoresistance and coercivity, which may be attributed to ill-defined interfacial boundaries between successive layers. Previous work exploring the frequency dependency of GMR has been done using microwave techniques to indirectly determine GMR. Our magnetoresistance data was obtained by replacing one side of a square loop antenna with a Co/Cu multilayer and measuring the impedance. No effect on the magnitude of the GMR, due to high frequency test signals, was observed for a frequency range from DC to 5.5 GHz.Dept. of Physics.
