This paper describes the magnetization of type-11 superconductors in the critical state, where the critical current density, J,, has a field dependence of the form J,( 6) = &A 1 + BIB,)". Explicit formulae are derived for the various branches of the complete high-field hysteresis loop. The geometry
Three different methods for the analysis of magnetic-relaxation data, M(t, T), are presented: In one model a spectrum, p (U), of activation energies U is considered, whereas the other model is based on the existence of a single barrier, permitting arbitrary dependences U(j~M), where j denotes the cu
