摘要

研究了超高磁场对$\ mathm {V_{1-x} W_{x}O_{2} (x=0.06)}$电子态的影响。由于从高温金属态转变为低温绝缘态，光传输随温度的降低而增加。我们用波长为2 μm的激光进行了光传输测量，发现超过100 T左右的超高磁场抑制了低温绝缘状态。

Megagauss-field effect on the metal-insulator transition in $\mathrm{V}_{1-x}\mathrm{W}_{x}\mathrm{O}_{2} (x = 0.06)$

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.
