The doping effect of magnetic impurity (p-CyDTV) on an organic radical spin-Peierls (SP) compound p-CyDOV (TSP = 15.0 K) has been studied by heat capacity measurement of the doped crystals (p-CyDOV) 1-x(p-CyDTV)x. The antiferromagnetic transition was observed at TN = 0.135, 0.290 and 0.164 K for the crystals with x = 0, 0.01 and 0.07, respectively. In the low doping region of x = 0 and 0.01, the antiferromagnetic order and the spin-Peierls state coexist, and at x = 0.07 the single phase of antiferromagnetic order is realized. The doping effect showed the similarity with that for an inorganic SP compound CuGeO3.
