Notes:
A low cost reproducible fabrication process has been developed to prepare La0.5Ca0.5MnO3 (LCMO) films with well distributed uniform nanoscale dots using pulsed-laser deposition. It was found that the growth of the dots was closely related to the strain in the film during the growth process. The diameter and density of dots could be controlled within the range of 30–120 nm and 2×108–2×109/cm2, respectively. The magnetoresistance effect of such LCMO films is also enhanced, which may be caused by the spin-dependent scattering of carriers due to the existence of the dots. © 2001 American Institute of Physics.
