Some Magnetic Properties of Thin Ferromagnetic Film with Enhanced Surface Exchange Interactions

Abstract

Thin S = 112 ferromagnetic film with exchange interaction enhanced near the film surface is considered in the Ising model. As a result the phase diagrams, the magnetization profiles, and magnetization curves for several particular cases are presented. A modified definition of the critical A , parameter for the thin film case is also proposed.Im Ising-Model1 wird eine ferromagnetische Schicht mit S = 112 und erhohter Austauschwechselwirkungin der Nahe der Schichtoberflache untersucht. Als Ergebnis werden Phasendiagramme, Magnetisierungsprofile und Magnetisierungskurven fur einige besondere Falle angegeben. Eine modifizierte Definition des kritischen A,-Parameters fur den Dunnschichtfall wird ebenfalls vorgeschlagen.

Magnetisation depth profiles in trilayer systems with mixed–spin interfaces—a contribution to temperature dependent GMR-potentials

“…The method is superior to the standard molecular field approach and thus it is particularly well suited for the description of mixed-spins as well as layered systems [22][23][24]. Very recently, a similar effective field approach has been applied to the simplest spin- 1 2 ML with double-plane interface considered as a stochastic binary alloy [25].…”

Magnetism in Ferromagnetic Spin-1/2 Ising Multilayers

“…In the films the surface magnetization maintains the same finite magnetization in the central atomic layers. [46] and Wiatrowski et al [47].…”

Thermodynamics of the small clusters: The Gibbs free-energy derivation for the Honmura–Kaneyoshi method

“…It is, among other things, the theory of disordered diluted alloys [3,14,15], random field problems [15,16], amorphization [14,17,18] and surface magnetism [4,19]. In the equivalent, integral operator version, the method has been applied to studies of thin magnetic films [20,21]. At the same time, great efforts were put into application of H-K method to higher spins problem [22,23].…”
