Enhancement of TC and reentrant spin-glass transition in La0.86Ca0.14Mn1-yCryO3 (y = 0, 0.1 and 0.2)
We report on the structural, frequency dependent ac susceptibility, dc magnetization and magnetoresistance (MR) measurements on polycrystalline samples of La0.86Ca0.14Mn1-yCryO3(y = 0, 0.1 and 0.2) prepared by sol-gel technique. For y = 0, a paramagn
