Abstract
Kerr loops measured in the 0th, –1st, and –2nd diffraction order beams on deep magneto-optic gratings show constructive and destructive interference of the beams reflected from grooves and lands as a function of effective phase depths and relative widths of grooves and lands. Hall-effect measurements yielded coercivities of grooves, lands, and sidewalls at different angles of the applied field. Sidewall reversals appear clearly in Kerr loops measured in the various diffracted beams, with signal amplitude depending on groove depth and the angle between the sidewall and the diffracted beam.
