摘要
A theoretical model deals with a structure of permanent dipoles of 'ordered clusters' (ferrons) in the amorphous films. The theoretical calculation is based on our experimental results of thin films of two amorphous materials (barium titanate and lead zirconate titanate). A statistical physics approach in accordance with the above ferron model, as well as a thermodynamic approach have been employed for calculation. The theoretical results agree very well with those from experiments. (C) 1999 Elsevier Science B.V. All rights reserved.
