Vortex Pinning and Dynamics in Perovskite Oxides: Thermal Magneto-Transport in the Mixed State

Broadening of the resistive transition in polycrystalline Bi/Pb-2223

“…The former probes a transport non-equilibrium effect, the latter informs us about the bulk screening response. It is also known that there are many vortex phases in the mixed state, in which the interplay between vortex motion and microstructure is hard to understand [15][16][17][18][19][20]. It was immediately noticed that grain boundaries and secondary phases as extended defects were to be considered as well as local defects.…”
