Abstract :
The temperature dependence of magnetization and coercivity for La0.7Ca0.3Mn1-xVxO3 (x = 0 and 0.1) was measured. The spin-glass-like phenomenon has been observed in the V-doped sample. The temperature dependence of magnetization behaves to match with that of the coercivity below the Curie temperature. It is suggested that the temperature dependence of coercivity for La0.7Ca0.3Mn0.9V0.1O3 is related to coexistence of the ferromagnetic and the antiferromagnetic orders, which is induced by the V doping at the Mn sites.
