Abstract

Hall experiments are carried out normally in bulk materials where a dc current is applied perpendicular to a static magnetic field. Since the dc Hall coefficient is small for type-II superconductors at temperatures well below the transition temperature Tc, the possibility of measuring the Hall coefficient of the superconductor under ac conditions is explored. It is found that the ac Hall coefficient can be readily detected through the measurement of the reflected microwave beam, whose polarization has been rotated 90° away from the incident wave irradiating on the surface of a high-Tc superconducting material biased by a dc magnetic field.
