Upper critical field for superconductors with edges and corners

Original article


The effect of non-smoothness of sample surfaces on the value of the upper critical field \(H_{C_3}\) and on the location of superconductivity nucleation is discussed. It is shown that, superconducting samples with edges and corners have higher value of \(H_{C_3}\) comparing to samples with smooth surfaces. Superconductivity nucleates first at the top and bottom edges in a cylinder with a finite height, and nucleates first at vertices in a cuboid.
