| 中文摘要 | Contiguously nanostructured networks of La0.67Ca0.33MnO3 (LCMO) are fabricated successfully by pulsed electron deposition (PED) onto the surface of porous anodic alumina oxide (AAO). The Curie temperature (T-C) is about 250 K. The metal-insulator transition temperature (T-p) is about 145 K without the magnetic field. The magnetoresistance can reach 84% near the peak temperature, which suggesting a strong magnetic correlated electronic transportation process. Zero field cooling (ZFC) and field cooling (FC) are split below the paramagnetic-ferromagnetic transition. The ZFC curves exhibit a typical blocking process. The observed spin glass and weak localization phenomena are due to the size effect, and it is found that the resistance dependent temperature curve above metal-insulator transition temperature (T-p) is more suitable to small polaron hopping (SPH) model.
