Giant magnetoresistance on low field in non-stoichiometric La2/3Ca1/3Mn1-xO3

Description
Electrical transport and low field magnetoresistance (MR) are reported in the La2/3Ca1/3Mn1-xO3 (x = 0-0.16) samples, which are prepared by the sol-gel method followed by a sintering treatment at 11000C. Experimental results show, for x = 0.06, an MR platform is observed in a temperature ∼200 K under the magnetic field of 0.5 T. With an increase in x, the MR effect gets augmented. For the sample with x = 0.16, its MR peak is as high as 50%
