Abstract
The development of a ''coherent'' field emission electron beam made it possible to directly and even dynamically observe phase objects such as superconducting vortices. Magnetic lines of force of individual vor tices were quantitatively observed as phase contour lines in a hologra phic interference micrograph, and the dynamics of the vortices were ob served by Lorentz microscopy. The interaction of vortices with pinning centers or lines in superconductors was investigated by direct observ ation. (C) 1997 Elsevier Science B.V.
