| 520 | |a Abstract 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 $ Gd_{0·7} $$ Sr_{0·3} $$ MnO_{3} $ is purported to be exhibiting unusual properties because of smaller ionic radius of Gd. $ Gd_{0·7} $$ Sr_{0·3} $$ MnO_{3} $ 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. | ||

On conduction mechanism in paramagnetic phase of Gd based manganites |
| abstract |
Abstract 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 $ Gd_{0·7} $$ Sr_{0·3} $$ MnO_{3} $ is purported to be exhibiting unusual properties because of smaller ionic radius of Gd. $ Gd_{0·7} $$ Sr_{0·3} $$ MnO_{3} $ 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. © Indian Academy of Sciences 2012 |

Abstract 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 $ Gd_{0·7} $$ Sr_{0·3} $$ MnO_{3} $ is purported to be exhibiting unusual properties because of smaller ionic radius of Gd. $ Gd_{0·7} $$ Sr_{0·3} $$ MnO_{3} $ 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. © Indian Academy of Sciences 2012 |
