✦ Synopsis

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 transition from isothermal to adiabatic limit of the flux propagation. Periodicity, size and ttme duration of the instabilities are discussed.
