Abstract

Most of the models purporting to explain the intriguing observation of colossal magnetoresistivity (CMR) in manganites invoke double exchange (DE) electron transfer between (formula presented) and (formula presented) ions, and coupling between the itinerant electrons and the dynamic Jahn-Teller (J-T) lattice distortions. Here we report using Mössbauer spectroscopy some very revealing commonalities in the magnetic behavior of (formula presented) which is representative of systems that do not exhibit DE electron transfer nor J-T distortions. These observations shed light on the origin of intrinsic CMR in general.
