Superconducting generator of electromagnetic pulses

An idea for the creation of active devices is proposed, based on flux jumps in layered superconductors. In a magnetic field slightly tilted to the layers a system of kinks on vortex lines can arise in such superconductors. Rotation of the sample leads to the existence of a kink structure even in a parallel magnetic field, since the planar pinning centers obstruct disappearance of the kinks. This is confirmed by the existence of a perpendicular component of the trapped magnetic field when the film is parallel to the external field under rotation. The transition of the lattice into the ground state with minimum energy should lead to the generation of an electromagnetic pulse; its output energy is equal to the sum of the energies of the kinks, which can be a significant part of the energy of the magnetic field in the sample.
