Experimental observation of charge ordering in nanocrystalline Pr${}_{0.65}$Ca${}_{0.35}$MnO${}_3$

Abstract

Observation of charge ordering in single crystalline and bulk polycrystalline systems of various rare-earth based manganites is well documented. However, there is hardly any manifestation of the same when the grain size is reduced to nanoscale. We have observed charge ordering in case of nanocrystalline Pr${}_{0.65}$Ca${}_{0.35}$MnO${}_3$ of average particle size 40 nm. This phenomenon is attributed to the primary role played by the martensitic character of the charge order transition in the material.
