Abstract

A new method for correlating the far infrared magnetorefractive effect (MRE) and giant magnetoresistance (GMR) is tested on commercially grown CoFe/Cu multilayers. Parameters are determined to demonstrate a simple relationship between prominent features of an MRE spectrum and the size of the electrical magnetoresistance. The results encourage the use of the new approach for sensing GMR in thin films
