High Critical Temperature Superconductor (IMAGE) Université de Genève Caption Artist's impression of a high critical temperature superconductor immersed in a magnetic field. The magnetic field generates whirls of current called vortices. These allow to better perceive an ordered electronic structure that coexists with the superconducting state.
