The rapid penetration of magnetic flux into a Meissner phase of the type-II superconductor is
studied analytically and numerically. A sharp shock wave front of the magnetic induction is …

Novel instability representing an avalanch-like penetration of the magnetic flux into
superconductor is explained in terms of thermomagnetic shock wave propagation. It is …

In recent experiments, trapped magnetic flux is initially generated by abrupt laser heating of
a strip of a type-II superconducting film subjected to a weak magnetic field. We study herein …

The perturbations induced by the varying current I or magnetic field may result in the
instability of the superconducting state at some I= I m< I s, where I m is the function of dI dt. It …

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 …

The critical state stability in a'hard'type-II superconductor with respect to the flux jumps has
been studied both for adiabatic and isothermal boundary conditions. The sample geometry …

The non-linear dynamics of the critical state in hard superconductors has been studied
taking into account the effect of dispersion and dissipation. Stationary thermomagnetic shock …

On the basis of a critical-state model it is shown that finite temperature perturbations strongly
influence the conditions for the occurrence of a thermomagnetic instability in a type-ll …

It is shown that a plane front of magnetic flux entering into a type-II super conductor
manifests an instability. This instability is caused by the positive feedback between the front …

Explosive instability is found for the first time to exist in the final stage of the evolution of
thermomagnetic disturbances in type-II superconductors. The new mechanism—nonlinear of …
