摘要：

The magnetic and transport properties of nanocrystalline La0.875Sr0.125MnO3 have been studied. Raw samples, prepared by the sol-gel method, were annealed at different temperatures to produce samples of particle sizes 18 nm, 36 nm, and 50 nm. Unlike bulk and single-crystalline samples of the same composition, magnetization data of the nanoparticle samples show no signature of structural transitions. The effects of particle size on the magnetic and transport properties have been attributed to the domain status, changes in the Mn-O-Mn bond angle, and Mn-O bond length in comparison with bulk samples. Field-cooled hysteresis measurements suggest a cluster glasslike behavior in the nanoparticle samples.
