Résumé

The vortex dynamics in the cubic (K, Ba)BiO₃ superconductor (T_c ∼ 30K) have been investigated by transport and magnetization measurements. We show that, close to the vortex glass transition line, the μ exponent characteristic of the creep phenomena (U ∼ J^-μ) presents a strong temperature and magnetic field dependence. We also show that this system presents a pronounced "fishtail" effect in the magnetization curves. The magnetic field dependence of the J deduced from this experiment is discussed.
