Titre : Relaxation processes in micromagnetics Type de document : document imprimé Auteurs : H. Suhl, Auteur Editeur : Oxford University Press Année de publication : 2007 Collection : International series of monographs on physics num. 133 ISBN/ISSN/EAN : 0-19-852802-7 Prix : 75 Langues : Anglais (eng) Résumé : Electrons in solids behave like microscopic bar magnets, and in certain solids these align to produce macroscopic magnetizations. This book deals with the dynamics of this magnetization field. It addresses questions of microscopic mechanism only to the extent that residual interactions of the magnetic moments with other degrees of freedom of the host solid affect the dynamics, particularly the dissipative aspects. Several of these damping mechanisms are evaluated here for their effect on the equations of the magnetization dynamics. This dynamics is intrinsically nonlinear. This is important in the applications, particularly magnetic recording, which involves very large motion of the magnetization, well beyond the validity of linearized (small motion) approximations or limited extensions thereof. Therefore nonlinear solution methods are emphasized, but with only minimal use of numerical simulation. The book should be useful to practitioners of magnetic recording, and to physicists studying magnetic phenomena. Relaxation processes in micromagnetics [document imprimé] / H.

Titre de série : IEEE Transactions on magnetics, Vol.34, No.4-1 Titre : Theory of the magnetic damping constant Type de document : articles et extraits Auteurs : H. Suhl, Auteur Année de publication : 1998 Importance : p. 1834-1838 Langues : Anglais (eng) Résumé : The aim of this paper is to express the effects of basic dissipative mechanisms involved in the dynamics of the magnetization field in terms of the one most commonly observed quantity: the spatial average of that field. The mechanisms may be roughly divided into direct relaxation to the lattice, and indirect relaxation via excitation of many magnetic modes. Two illustrative examples of these categories are treated; direct relaxation via magnetostriction into a lattice of known elastic constant, and relaxation into synchronous spin waves brought about by imperfections. Finally, a somewhat speculative account is presented of time constants to be expected in magnetization reversal
