| 中文摘要 | Effects of chemical etching and thickness on the transport property of La2/3Ca1/3MnO3 films are experimentally studied. Chemical etching produces a decrease of the metal-insulator transition from T-p = 263. to 23 5 K in addition to increasing the overall resistance of the film. Further etching does not change T-p while leads to a new resistive transitions at similar to 150 K. In contrast, film thickness influences the resistive behavior of the films strongly below 40 run, resulting in a sharp drop of Tp and a steep increase of the resistivity with the decrease of thickness. Reducing film thickness and chemical etching produce similar effects except for that the latter thins the film unevenly, which causes the occurrence of multi-resistive transitions. No visible effects associated with the enhanced surface roughness due to chemical etching are observed. (C) 2003 Elsevier Science B.V. All rights reserved. |
