Özet
In superconducting materials, a phase transformation occurs at critical transition temperature, Tc, and they show zero resistivity below Tc. The relation between zero resistivity and superconducting properties is an interesting and important issue to understand the mechanism of superconductivity especially for high-Tcsuperconductors (HTSCs). To determine the behavior of superconducting materials under an applied magnetic field, many remarkable studies that have been conducted due to their great technological and industrial importance. The magnetic field causes a change in the transition temperature, the width of resistance transition and activation energy of superconducting materials. Energy dissipation is one of the important obstacles to obtain superconducting material with desired properties for practical industrial applications. Thus, some important models that make an explanation about the dissipation mechanism have been explained and interpreted. The critical current density has been discussed with early and recent models, experimental methods, and recent studies on HTSCs. In addition, a transverse voltage difference (the Hall voltage) can be observed in superconductor materials, especially in HTSCs, under perpendicular magnetic fields. But, the sign of Hall voltage becomes opposite to the ordinary Hall effect. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
