The de Haas–van Alphen effect was observed in the underdoped cuprate YBa 2 Cu 3 O 6.5
via a torque technique in pulsed magnetic fields up to 59 T. Above a field of∼ 30 T the …

The flux jump instability of Bean's critical state in the flux-creep regime of type-II
superconductors is considered. We find the flux-jump field B j which determines stability …

Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II
superconductor films is crucially important for their application. If some vortices get detached …

The thermomagnetic flux-jump instability of the Bean critical state is considered, which may
occur during flux penetration in thin films of type-II superconductors in a perpendicular …

We report the results of numerical simulations of flux jumps on the basis of dynamic process
of thermomagnetic interaction to the nonisothermal and nonadiabatic high-T c …

The flux jump in bulk superconductors is accompanied by a rapid change in temperature
and magnetic field, which can induce change in electromagnetic bodyforce and thermal …

Thermomagnetic instabilities are widely observed in bulk superconductors and
superconducting (SC) films in form of flux jumps and flux avalanches. Recent experiments …

We report torque magnetization measurements in regions of the mixed state phase diagram
(B∼ μ o H c 2 and T c/10 3) of the organic superconductor κ−(ET) 2 Cu (NCS) 2, where …

The stability of superconducting films with respect to oscillatory precursor modes for
thermomagnetic avalanches is investigated theoretically. The results for the onset threshold …

We have performed magnetization measurements on a Pb thin film perforated by a square
array of antidots in a broad temperature range. For temperatures below 6 K, we observe …
