Abstract
A comparative investigation has been conducted on the nanowires and nanoparticles (both in the size range of 20–35 nm) of Ca0.82La0.18MnO3, finding that the nanowires have similar magnetic properties to the bulk, whereas the nanoparticles behave evidently different. In the nanoparticles, charge ordering and antiferromagnetic phase disappear; instead, a ferromagnetic transition is observed. Analysis of the crystal structure indicates that, for nanosized manganite systems, whether charge ordering is suppressed and ferromagnetism is developed as the size scales down depends on the level of intrinsic structural distortions; nanodimensional effect or surface effect is not determinant.
