抜粋

Flux-creep-induced relaxation of persistent current was investigated close to Tc in a ring-shaped grain-aligned Y1Ba2Cu3O7-σ (YBCO) with the c-axis perpendicular to the ring's plane. The results revealed two distinct relaxation regimes: a steady-state logarithmic relaxation of the persistent current from an initial value Jo ≅ Jc with the energy barrier Ueff(J) = Uo(1-J/Jc) where Uo ≅ 0.4 eV, and a non-steady-state (non-lo garithmic) one from Jo < - 0.8 Jc, with Ueff(J) = constant at fixed value of time.
