Microwave-Assisted Reverse Micellar Synthesis of Sm0.42Ca0.58MnO3 Nanoparticles

Abstract

Abstract The control of size and dispersity of particles is a crucial aspect of nanoparticle preparation. In this work we report on microwave assisted reverse micelle method of preparation of nanoparticles of the doped rare earth manganite Sm0.42Ca0.58MnO3 and compare the results with those obtained from conventional sonication assisted reverse micelle method. We find that the microwave assisted method enables the preparation of particles of smaller size and minimal polydispersity. The study of such particles may lead to the resolution of the longstanding issue of the nature of the charge order (CO) melting in nanomangnites, namely whether the size induced melting of CO in nanomangnites is complete or some residual short-range CO still persists.
