Abstract

A miniaturized float zone technique using laser heating has been found to have potential for producing superconducting fibers of Bi2Sr2CaCu2O8 which can carry high currents. Growth stability and growth rate, however, need to be improved if this technique is to be useful for preparing long lengths of 30 μπι diameter high quality fibers for property evaluation and prototype devices. One of the first requirements toward achieving this goal is the preparation of dense, homogeneous starting material. Work on different strategies for starting material preparation are discussed.
