Charge ordering in Nd1=2Sr1=2MnO3 Nanoparticles

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.

Modification of the Charge ordering in Pr$_{1/2}$Sr$_{1/2}$MnO$_{3}$ Nanoparticles

Transport and magnetic properties have been studied in two sets of sol-gel prepared Pr$_{1/2}$Sr$_{1/2}$MnO$_{3}$ nanoparticles having average particle size of 30 nm and 45 nm. Our measurements suggest that the formation of charge ordered state is largely affected due to lowering of particle size, but the ferromagnetic transition temperature ($T_{C}$) remains unaffected.
