|Title:||Comment On "generalized Stoner-wohlfarth Model And The Non-langevin Magnetism Of Single-domain Particles" By M.a. Chuev|
|Author:||De Biasi E.|
|Abstract:||The model recently proposed by M.A. Chuev [JETP Lett.85, 611 (2007)] has been analyzed. It has been shown that the anisotropy corrections near the blocking temperature always lead to a magnetization lower than the equilibrium value, contrary to the findings in Chuev's work. In addition, the asymptotic high-temperature limit of Chuev's model is inconsistent with the expected thermodynamic limit. Moreover, even at a low temperature, only a careful implementation of this theory can guarantee arriving at the correct result, avoiding some wrong conclusions in Chuev's work. © 2008 Pleiades Publishing, Ltd.|
