High Tc Superconductors in Pulsed Magnetic Fields
Abstract
The study of high temperature superconductors (HTSC) in pulsed high magnetic fields is discussed. Due to the high critical temperature Tc of the HTSC, the critical fields are unusually large. As a rule of thumb, each degree below Tc requires a magnetic field of about 1.5 T to suppress superconductivity (e.g. 150 T for Tc = 100 K), in order to study the normal state. At the high temperatures where the superconducting state exists, the physical properties are very sensitive to thermal fluctuations. Due to the fast relaxation, it is advantageous to use pulsed fields where the short pulse duration allows measurements before relaxation occurs. Therefore, experiments in pulsed magnets can shed light on some of the otherwise inaccessible physical properties of the HTSC.
