Abstract

We report local studies of magnetic-field-modulated microwave reflectivity (MFMMR) of high-T_c superconductors using a near-field scanning aperture probe operating at 96 GHz. The MFMMR signal appears as a sharp peak at transition temperature and is very useful in identifying superconducting phases in multiphase samples. We show that MFMMR is qualitatively different from such a routine characterization tool as inductive technique. Simultaneous MFMMR and inductive measurements allow us to distinguish between the surface and bulk superconducting properties. The MFMMR technique may be easily extended for the study of giant magnetoresistance materials.
