Materials belonging to the family of manganites are technologically important since they exhibit colossal
magneto resistance. A proper understanding of the transport properties is very vital in tailoring the properties. A
heavy rare earth doped manganite like Gd0·7Sr0·3MnO3 is purported to be exhibiting unusual properties because
of smaller ionic radius of Gd. Gd0·7Sr0·3MnO3 is prepared by a wet solid state reaction method. The conduction
mechanism in such a compound has been elucidated by subjecting the material to low temperature d.c. conductivity
measurement. It has been found that the low band width material follows a variable range hopping (VRH) model
followed by a small polaron hopping (SPH) model. The results are presented here |
