HIGH-TEMPERATURE SUPERCONDUCTORS - DEPENDENCE ON PRESSURE AND APPLICATIONS IN ACOUSTICS, AN ANALYSIS OF THE IMPURITY MECHANISM

By using a thesis following from the impurity mechanism-a change in pr essure is analogous to a change in the doping of a superconductor-the relations for pressure derivatives of various parameters (critical tem perature, resistance in the transition region, etc.) are obtained, and their maxima are found. The derived relationships are compared with t he results of experiments. Promising devices, which use variations of these parameters with pressure, are discussed.
