Abstract
Studies have been performed on a series of La-modified lead zirconate titanate (PLZT) specimens with grain sizes between 0.6 and 6 mu m by d ielectric spectroscopy and transmission electron microscopy. These inv estigations have revealed an increase in the degree of relaxer charact eristics with decreasing grain size for tetragonal-structured PLZT. In addition, small grain sizes were found to favor tweed-like structures and polar nanodomains, over normal micron-sized ferroelectric domains .
