Tuning the growth pattern in 2D confinement regime of Sm2O3 and the emerging room temperature unusual superparamagnetism.

摘要: Programming the reaction chemistry for superseding formation of Sm2O3 in a competitive process and dissolution, crystal growth patterns are varied two different nanostructures 2D confinement regime designed. Among these, regular self-assembled square platelets exhibit paramagnetic behavior analogous to bulk Sm2O3. But, other one, flower like shaped nanostructure, formed by irregular growth, shows superparamagnetism at room temperature which is unusual paramagnet. It has been noted that variation pattern due difference binding ability organic ligands, oleylamine oleic acid, used synthesis magnetic related defects incorporated during growth. Herein, we inspect plausible origin contrasting magnetism these
