摘要：

Transport and magnetic properties have been studied in two sets of sol-gel prepared Pr1/2Sr1/2MnO3 nanoparticles having an average particle size of 30 and 45 nm. Our measurements suggest that the formation of a charge-ordered state is largely affected due to lowering of the particle size, but the ferromagnetic transition temperature (T-C) remains unaffected.
