Opis:: We present the results of the impedance measurements in Nb$\text{}_{3}$Al superconducting polycrystalline alloy vs. temperature and magnetic field. Using these results and applying the size effect model we calculate the flux-flow conductivity of the Nb$\text{}_{3}$Al superconducting alloy near its critical temperature.

Opis:: We investigated dynamics of the thermomagnetic avalanche development in melt-textured samples of the oxide YBaCuO high temperature superconductor. We found that the flux jumps, caused by the thermomagnetic instabilities, are accompanied by giant convergent oscillations of the surface induction. These results are compared with the dynamics of the flux jumps in other type-II superconductors, including conventional NbTi and oxide high temperature Bi $\text{}_{2}$Sr$\text{}_{2}$CaCu$\text{}_{2}$O$\text{}_{8+δ}$ superconductor, and discussed in the framework of the available model of the thermomagnetic avalanche development.

Opis:: Magnetostriction of a large slab of conventional NbTi superconductor, with a diameter of about 6 mm, was investigated by the strain gauge technique. At the temperature of 4.2 K and in the external magnetic field of several T we found irreversible magnetostriction of an order of 10$\text{}^{-5}$, where the number means the relative changes of the slab diameter. This large magnetostriction is accompanied by giant magnetostriction jumps, caused by thermomagnetic avalanches. These thermomagnetic avalanches also cause giant jumps of the surface magnetization, which can be observed by using the Hall probes. The results were analyzed in the framework of the pinning induced magnetostriction model.
