Correlation between extrinsic electroresistance and magnetoresistance in fine-grained La0.7Ca0.3MnO3

P. Sujatha Devi, A. Kumar, Dipten Bhattacharya +2

We report our observation of a correlation between the extrinsic electroresistance (EER) and magnetoresistance (EMR) via grain size in fine-grained La0.7Ca0.3MnO3. The nature of de…
