Abstract
A response is given to critical and erroneous comments on my results reported in Pis’ma Zh. Éksp. Teor. Fiz. 85, 744 (2007) [JETP Lett. 85, 611 (2007)]. A more accurate magnetic dynamic model has been proposed for the calculation of the magnetization curves of an ensemble of single-domain particles. The preliminary calculations confirm that the asymptotic behavior in weak magnetic fields differs from the Langevin limit.
