Abstract

Effects of ultrahigh magnetic fields on the electronic state of \mathrm{V-{1-x} W-{x}O-{2} (x=0.06)} are investigated. Optical transmission increases with decreasing temperature due to the transformation from the high-temperature metallic state to the low-temperature insulating state. We have made optical transmission measurements with 2 μm wavelength laser light, and found that the low-temperature insulating state is suppressed by ultrahigh magnetic fields exceeding around 100 T.
