Charge ordering in Nd1=2Sr1=2MnO3 Nanoparticles
Anis Biswas, I. Das
Abstract
Nanoparticles of Nd1=2Sr1=2MnO3 of average particle sizes 12 nm and 25 nm are prepared by sol-gel technique. Transport, magnetotransport, magnetization and I-V characteristics studies have been performed on the nanoparticles. Although the particle size is order of magnitude smaller than the correlation length of charge ordering of the bulk material,the existence of charge ordered state has been observed in the nanoparticles at low temperature.
