✦ Synopsis

By varying the content ratio of the initial products, nine compounds of the Y-Ba-Cu-0 system have been produced. These were studied to find their T, values, critical currents j , at 77 K and effects of compression stress on the U(j)-curves. Mechanical loading has been found to result in a shift of the U(j)-curve towards a larger current. A correlation between the critical current value, the slope of the U(j]-curve, and the stress induced shift is shown to exist. Samples with equal absolute deviations from the stoichiometric composition reveal close properties, the better the smaller is the deviation.
