The giant magnetoresistance of Co/Cu superlattices grown by MBE
Abstract We report the first observation of a giant magnetoresistance (MR) in Co/Cu superlattices grown by MBE. The maximum value of the MR is - 26% and this is found in a specimen for which theExpand

Systematic study of molecular beam epitaxy growth and magnetic properties of Fe on Au(111)
We have grown a series of Fe samples on Au(111) by molecular beam epitaxy. Fe was grown on Au at 30 °C and shows clear reflection high energy electron diffraction (RHEED) oscillations up to 8Expand
