Abstract:

The first observations of uv optical and magneto-optical spectra for bulk, single-crystal ferric oxide compounds are reported. Measurements were made on rare earth orthoferrites, rare earth iron garnets, nickel ferrite, and ferrimagnetic magneto-plumbite. In particular these results include the first uv measurements of the complex polar Kerr effect for any material. The magneto-optical measurement technique complex polar Kerr effect is discussed, the experimental hardware is described, and the data is analyzed in terms of a molecular orbital theory which elaborates on earlier theories by Clogston.
