Fig. 4: Magnetic-field dependence of the optical transmission at 14 and 131 K.
From: Magnetic-field-induced insulator–metal transition in W-doped VO2 at 500 T

The transmission is plotted before the breaking point of the destructive measurement. The shaded area indicates transmission lower than that in the high-temperature metallic phase at 291 K. Inset: transmission change ΔTrans. as a function of the magnetic field. The dashed yellow line corresponds to ΔTrans. = 0. The red and purple arrows indicate the field positions (B*) where ΔTrans. deviates from zero.
