In this paper we report the structural and property (magnetic and electrical transport) measurements of nanocrystals of half-doped La 0.5 Ca 0.5 MnO 3 (LCMO) synthesized by chemical route, having particle size down to an average diameter of 15 nm. It was observed that the size reduction leads to change in crystal structure, and the room temperature structure is arrested so that the structure does not evolve on cooling unlike bulk samples. The structural change mainly affects the orthorhombic… 
Stability of charge and orbital order in half-doped Y0.5Ca0.5MnO3 nanocrystallites

Magnetic phase diagram of nanosized half-doped manganites: role of size reduction.
It is proposed that the reported exotic phenomena in the nanosized half-doped manganites should be mainly ascribed to surface disorder effect, and a detailed analysis on the magnetic susceptibilities and the ESR linewidths reveals that for the two compounds the size reduction weakens both the ferromagnetic and antiferromagnetic interactions, and converts the long-range charge orderings to short-range ones.
