Spinwaves in spintronics structures

We have been applying in situ and ex situ spin-wave Brillouin Light Scattering (BLS) techniques to spinwave structures we are growing by Molecular Beam Epitaxy (MBE). The sensitivity of our BLS technique is illustrated by our ability to measure spin-wave excitations for samples as thin as 1 monolayer of Co buried by as much as 20 nanometers of Au. This talk will describe the use of in situ and ex situ BLS in combination with appropriate structural probes to determine the origin of several interesting and useful physical phenomena in spintronics structures.
