Magneto-optical spectroscopy of magnetic multilayers: Theory and experiment (A review)
Experimental and theoretical results on the optical and magneto-optical (MO) spectral properties of a series of Co/Cu, Co/Pd, Co/Pt and Fe/Au multilayers (MLS) are reviewed. Diagonal and off-diagonal components of the optical conductivity tensor have been determined in the photon energy range 0.8-5....
