摘要	The 0.5Bi(0.8)La(0.2)FeO(3)-0.5PbTiO(3) (BLF-PT) solid solution nanoparticles of different particle sizes are prepared using sol-gel method and characterized in terms of the size-dependent crystal structure, Raman scattering, dielectric susceptibility, and magnetism. Upon decreasing particle size, the crystal structure evolves from tetragonal symmetry to rhombohedral one, and a substantial enhancement of magnetization is observed. These size-dependent effects are reasonably explained by a simple thermodynamic scenario and first-principles calculation based on the BLF-PT multilayer model. (C) 2010 American Institute of Physics.
