Spin Polarized Studies of Iron Oxide Films
EMSL Project ID
1757
Abstract
We are presently studying Fe3O4 films using spin polarized photoelectron spectroscopy at the Advanced Light Source. We see initial indications of half-metallic, ferromagnetic behavior. (Half Metallic, ferromagnetic thin films hold the promise of being spin sources on the next generation of spin based devices.) But our analysis is hampered by the absence of clean surfaces and true surface characterization. We believe that Iron oxide films provided by Scott Chambers may be the key to resolving all of these questions. Scott will prepare the samples at PNL, perform surface characterization there, then bring the samples down to us at the ALS using vacuum suitcase technology. Once at the ALS, we will mount the samples and perform spin polarized measurements on Beamline 7.0 at the Advanced Light Source, using our spin resolving Spin Spectrometer.
