Numerous dopant ions were introduced into chromium dioxide at 65 kbar and 1200°C. The effect of 2 mole percent Fe, Ir, and Ru was to raise T c by 19°, 4°, and 2°, respectively. The effect of 2 percent of 2 percent V, As, Sb, Re, Mo, and W was to lower T c by 20°, 21°, 10°, 37°, 38°, and 42°, respectively. The saturation moment of the V-, As-, Re-, and W-doped samples was not reduced by more than 4 percent. With the exception of the As-doped sample, the cell dimensions are consistent with the substitution of M 5+ +Cr 3+ for 2 Cr 4+ or M 6+ +2 Cr 3+ for 3 Cr 4+ .
