Fig. 6

Δα/(αM − αI) is plotted as a function of magnetic field. αM and αI are defined as the α in the metallic and insulating phases at zero fields, respectively. Δα is the magnetic-field-induced change in the α. The ratio of the measurement temperature T to TMI for each film is 35/295  ≈  0.12 for VO2, 27/195  ≈  0.14 for x = 0.036, and 14/100 = 0.14 for x = 0.06.
