AN ORGANIC CHARGE TRANSFER SALT SHOWING SUPERCONDUCTING BEHAVIOUR.

Type of article: Article

Summary

THE MATERIAL, THE DI-TETRAMETHYL-TETRASELENAFULVENE HEXAFLUOROPHOSPHATE, (TMTSF)2 PF6, IS THE FIRST ORGANIC SOLID TO SHOW SUPERCONDUCTING BEHAVIOUR; THE SUPERCONDUCTING TRANSITION OCCURS AT ABOUT 1.3 K AND 6 KBAR PRESSURE. MOREOVER, IN THE NORMAL STATE, IT SHOWS A METAL-INSULATOR TRANSITION; AT ABOUT 12 K, THE MATERIAL BECOMES SEMICONDUCTOR. IF PRESSURE IS INCREASED, THE TRANSITION TEMPERATURE DROPS UNTIL EVENTUALLY THE MATERIAL BECOMES SUPERCONDUCTING. ELECTRON SPIN RESONANCE MEASUREMENTS SUGGEST THAT THE METAL-INSULATOR TRANSITION IS OF MAGNETIC ORIGIN, WHICH IS CONFIRMED BY STATIC MAGNETIC SUSCEPTIBILITY MEASUREMENTS IN THE SEMICONDUCTING STATE.
