论文摘要
三维导体中的纵向电流伴随着样品大体中的横向磁场。在样品散装中没有横向电流需要横截面中的非零霍尔电场，这提供了洛伦兹力取消。纵向电流本身可以看作是交叉磁性和电动（HALL）场中载体的集体漂移。在低温下，增强的载体粘度会导致不均匀的电流流动，其横向轮廓对$ collinear $ diamagnetic Currents在样品内壁上的存在敏感。以前的耗散性纵向电流在某些临界温度下纯粹变为流动性。超导性设置。电流和横向磁场从样品散装向内壁推出。样品的磁性质类似于理想diamagnet期望的磁性。计算超导性的阈值是针对任意温度，无序强度，样本量和电流以及（或）磁场强度的。已经研究了样品大小和磁场驱动的从正常金属相到超导性的过渡。不讨论超导阶段。
The longitudinal current in a three-dimensional conductor is accompanied by transverse magnetic field in a specimen bulk. The absence of the transverse current in a sample bulk requires a nonzero Hall electric field in transverse cross-section which provides the Lorentz force cancelation. The longitudinal current itself can be viewed as a collective drift of carriers in crossed magnetic and electric(Hall) fields. At low temperatures the enhanced carrier viscosity leads to nonuniform current flow whose transverse profile is sensitive to presence of $collinear$ diamagnetic currents at the sample inner walls. Former dissipative the longitudinal current becomes purely diamagnetic at certain critical temperature. The superconductivity sets on. The current and transverse magnetic field become pushed out from the sample bulk towards the inner wall. Magnetic properties of a sample resemble those expected for ideal diamagnet. The threshold of superconductivity is calculated for arbitrary temperature, disorder strength, sample size and current and(or) magnetic field strength. Sample-size and magnetic field driven transition from normal metal phase to superconductivity has been studied. The superconductivity phase is not discussed.
