Magnetic instabilities in single-crystaUme samples of l~gh temperature superconductors have been studied by magnetocaloric and magnetization measurements under varying magnetic fields. Sharp repetitive jumps are observed and are interpreted as been caused by the avalanche-like flux flow and the tran
Very detailed flux creep and relaxation measurements ofintragrain magnetization in sintered high-To superconductors at 4.2 K are presented. The M-relaxation rate is not a single valued function of the applied B-field but depends strongly on the prior magnetic field cycling procedure. The largest rel
