Abstract

Epitaxial Fe/Cr superlattices with negligible intralayer scattering have been grown on MgO(100) using MBE. The careful structural analysis of such superlattices prepared under different conditions reveals the details of the interfacial origin of the giant magnetoresistance (GMR). We find the highest GMR in samples with minimum intermixing but an enhanced density of steps at the interfaces. Such Fe/Cr superlattices display GMR amplitudes up to 220%.
