Аннотация
The creep of tin single crystals is investigated in the 1.6–3.7°K range and the influence of the superconducting transition is studied. The creep curves are described by a logarithmic law. The temperature and strain dependence of the enhanced plasticity effect are studied, and the stagelike nature of the latter is shown. Good agreement is obtained between experimental results and the predictions of the fluctuation theory of plasticity enhancement.
