We report on two types of experiments with intrinsic Josephson systems made from layered high-T-c superconductors which show clear evidence of nonequilibirum effects. (1) In two-point measurements of IV curves in the presence of high-frequency radiation a shift of the voltage of Shapiro steps from the canonical value V-s=hf/(2e) has been observed. (2) In the IV curves of double-mesa structures an influence of the current through one mesa on the voltage measured on the other mesa is detected. Both effects can be explained by charge imbalance on the superconducting layers produced by the quasiparticle current, and can be described successfully by a recently developed theory of nonequilibrium effects in intrinsic Josephson systems.
