Experimental Evidence: Exchanged Polarons Introducing Ferromagnetic Ordering in Strongly Correlated Electronic Materials of Doped Manganites
-
Abstract
We present direct experimental evidence that ferromagnetic (FM) transition in doped manganites is introduced by exchanged polarons rather than `bare' eg electrons and the FM transition depends on hopping energy of polarons regardless of variation of experimental methods. The observed universal relationships between polaron hopping energy and FM transition suggest a simply polaron exchange picture for understanding the origin of FM ordering in the complex strongly correlated electronic materials of manganites.
