Observation of Vortices

Abstract

Various kinds of special techniques have been developed to visualize quantized magnetic flux in superconductors, i.e. Vortex. This chapter reviews the experimental techniques and discusses the vortex distributions in high-T-c superconductors under various conditions. As currently available techniques, the Bitter method, the magneto-optic method, the scanning SQUID microscope, and terahertz radiation imaging are used in the study
