  • Abstract
    Basic dissipative and voltage-current curves of high-T/sub c/ conductors with normal metal matrix are obtained directly from the description of thermally activated flux creep. The effect of different criteria for j/sub c/ is discussed, and current sharing between superconducting and normal layers is analyzed. A comparison with the critical-state model is given. Intensive creep is shown to change considerably the real characteristics of high-T/sub c/ composites, increasing their thermal stability.<>
