Fig. 2: Temperature dependence of electrical resistivity and optical transmission of a V1−xWxO2 (x = 0.06) thin film.
From: Magnetic-field-induced insulator–metal transition in W-doped VO2 at 500 T

a Temperature dependence of electrical resistivity (ρ). The arrows indicate heating and cooling processes. b Temperature dependence of the optical transmission at 1.977 μm. The transmission measured in cooling process and that in heating process are represented with blue open squares and green open circles, respectively. The error bar is as large as the size of the square and circle marks in the plot.
