Magnetic, Electronic and Thermal Properties of Magnetic Multilayers
Abstract
This report describes research done under this project on the basic physics of magnetic multilayers. The work done covered both fundamental and applied problems. Among the problems studied were: 1) Surface phase transitions and spin wave modes in Fe/Cr superlattice. This project was a collaboration with Argonne National Labs and the theoretical calculations explained the experimental results showing an extra peak in the magnetic susceptibility was due to a surface phase transition. 2) Electromagnetic response of magnetic materials. Here we studied the interaction of high frequency EM waves (10 - 100 GHz) with structured magnetic materials. We also studied higher frequency modes (100-1000 GHz) in antiferromagnets 3). The influence of eddy currents on bulk and surface spin wave modes in metallic ferromagnets 4). Exchange Biasing - We showed that the spin wave frequencies of a thin Fe film could be increased substantially by coupling a Fe film to SmCo. A multilayer of Fe/SmCo could be used as an active element in a notch filter at high frequencies.
