Abstract
Thin Nb3Sn films on bendable quartz substrates have been prepared by different methods. These films exhibit an initial tensile stress. Bending the samples by two methods under known conditions results in quantitative changes of tensile stress and in relative changes of the superconducting transition temperature. On the average a “tension coefficient” of about
has been found for all samples. A certain influence of the preparation conditions has been observed. The results are in fairly good agreement with similar types of earlier measurements.
