Magnetic-Field-Induced Insulator Metal Transition of W-doped VO2 Observed by Electromagnetic Flux Compression at ISSP

The metal???insulator transition is one of the most fascinating phenomena in condensed-matter physics and has attracted much attention from researchers. It has recently been discovered that W-doped vanadium dioxide (V1???xWxO2) exhibits a magnetic-field-induced insulator???metal transition in a very high magnetic field of 500 T. Electromagnetic flux compression (EMFC) is essential for experiments involving this kind of ultrahigh magnetic field. Experimental findings regarding the field-induced insulator???metal transition in V1???xWxO2 are summarized including new experimental results for pure VO2, and a possible mechanism of the phase transition is discussed. The technical details required for EMFC experiments are also introduced. Promising research themes in ultrahigh magnetic fields of up to 1000 T are proposed as future prospects for ultrahigh magnetic field research at the Institute for Solid State Physics (ISSP).
