概要

論文の詳細を見る
Measurements and analysis of spectroscopic reflection ellipsometry and magneto-optical polar and longitudinal complex Kerr effect are reported on a natural (111) face of a high quality NiFe_2O_4 single-crystal.The experimental reflection data is expressed in terms of the permittivity tensor.This information is employed in modeling experimental polar Kerr spectra of a NiFe_2O_4 film and a satisfactory agreement has been achieved.These results demonstrate the importance of the spectroscopic magneto-optic reflection ellipsometry in the diagnostics of magnetic oxide films with thicknesses in the range 10~1 to 10~2 nm.
