摘要

A method for local magneto-optical Kerr effect imaging based on a home-made scanning near-field optical microscope working in reflection mode is presented.Shear force detection is carried out by using a symmetric piezoelectric bimorph sensor,which provides an easy way not only for probe-surface distance control but also for imaging.Polarization-preserving fiber probes used as a local optical detector are fabricated with a heating-pulling technique and the probes'' polarization properties are measured.Shea...
