(a) MFM and [(b)–(d)] AFM images of magnetic gratings. MFM and AFM images were taken from the same scan area and position.
Hysteresis loops of of (a) the zeroth-order and (b) the negative first-order diffracted beams. Lines are guide to the eyes only.
Kerr rotations of the zeroth- and the negative first-order diffracted beams as a function of grating depth. Solid lines are the results of simulation.
Off-diagonal components of dielectric tensor determined by simulation.
