ADDITIONS AND CORRECTIONS 2006, Volume 110B G. Wang, W. J. Tian, and J. P. Huang*: Response of Ferrogels Subjected to an AC Magnetic Field In the original article (J. Phys. Chem. B 2006, 110, 1073810745), Figures 1 and 2 were plotted incorrectly. They should be corrected as Figures 1 and 2 herein. In addition, eq 23 in the original article appears incorrectly, and it should be
gL ) 1 -
[
Correspondingly, Figures 5 and 6 in the original article should be corrected as Figures 5 and 6 herein. The remaining formalism and the overall discussion of the results as well as the conclusions of the original article are not affected. This is because only quantitative (rather than qualitative) results are changed slightly.
