Abstract:In the present communication, a systematic study of electrical, structural, and thermal measurements is done for low bandwidth compounds of Dy 1−x Sr x MnO 3 . All the samples are prepared using solid-state reaction method. XRD patterns were refined using Rietveld method, and it is seen that all the compounds are single phased. It is demonstrated that the small polaron hopping (SPH) model valid for high-temperature regime, whereas in the low-temperature regime, the variable-range hopping (VRH) model is valid. … Show more
