This review treats magnetic instabilities in hard and combined Type II superconductors. We give and discuss in detail the criteria for stability of the critical state with respect to magnetic-flux jumps. We study the effect of magnetic and thermal diffusion, as well as that of the structure of a combined superconductor, on the magnetic-field value for a flux jump. The theoretical results are compared with the existing experimental data.
