Notes:
A scanning near-field optical microscope is combined with a modified Sagnac interferometer to generate high-resolution magnetic contrast images of a magneto-optical disk (MOD) in reflection. The interferometer acts as a magnetic sensor to determine the Kerr rotation of reflected circularly polarized light. A separate shear-force sample topography is obtained simultaneously with the optical. This technique allows successful magnetic imaging of samples with complicated surface topographies, as demonstrated with the MOD. For these initial measurements, the resolution with nonmetal-coated fiber tips is 300 nm, and the magnetic phase sensitivity is 1 mrad. © 1998 American Institute of Physics.
