Electromagnetic fieldsSuperconductorsFerromagnetismA comparison is made between the treatment of magnetic fields in superconductors and normal materials. First some history is given, showing how early workers anticipated vortices. Later treatments tried to build a macroscopic theory using forces and torques ...
From the outset of superconductivity research it was assumed that no electrostatic fields could exist inside superconductors, and this assumption was incorporated into conventional London...doi:10.1002/andp.201900212J. E. HirschDepartment of Physics...
Microwave Absorption of Superconductors in Low Magnetic FieldsThe results of modulated microwave absorption experiments on ceramics, thin films and single crystals of YBa 2 Cu 3 O 7–δ are described with emphasis on the different behavior of the various forms. All show microwave losses due to ...

Here we measure the current–voltage characteristics of superconducting films at low temperatures and high magnetic fields. Using heat-balance considerations we demonstrate that the current–voltage characteristics are well explained by electron overheating enhanced by the thermal decoupling of the electrons ...
