  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.
