The Williamson-Hall method was used in order to determine the microstrain and compare the crystallite size achieved using Scherrer's method. The values indicated in Table I and Figs. 2(a) and 2(b) of the original article1 are incorrect. The Williamson-Hall method was used to determine the microstrain and the crystallite size; the ? cos ? values are plotted as a function of 4 sin ?; the results presented indicate that the slopes are negative;1 unfortunately, this was because when calculations were made to graph ? cos ? as function of 4 sin ?, the angles of the reflections that were taken were not divided by two, which resulted in obtaining negative slopes. According to Fig. 2, all the slopes are positives, and this behavior is associated with shrinkage strain into the crystalline structure of the oxide, which leads to the formation of a great quantity of defects (mainly dislocations). Figures 2(a) and 2(b) were corrected and the values of Table I were again calculated and the corrected table is as follows.
