- Abstract
Magnetic properties of La0:8K0:2MnO3 have been studied on nanoparticles prepared by glycine-nitrate method. Crystal structure and particles size were modified by heat treatment. Crystal structure changes from orthorhombic (space group Pbma) to rhombohedral (space group R-3c) after annealing at 600°C/2 hours. The average size of particle varies with annealing from about 30 nm to 135 nm. The Curie temperature TC and the saturated magnetization μs increase with annealing. The exchange bias effect was observed on samples with particles size smaller than 60 nm.
