Phase transitions of ferromagnetic Ising films in a transverse field

Dynamical Properties of Thin Ferroelectric Films Described by the Transverse Ising Model

“…The surface also causes the critical value J sc to be shifted to a higher value. The results are in agreement with those obtained by the effective field theory [21]. We turn in this paper to the influence of temperature on the dynamical behaviour of thin films.…”

Phase Transitions in a Spin‐1/2 Ising Model of Alternating Magnetic Superlattice

“…Now we obtain the critical temperature from the condition given by det M bulk 0 19 from which we find T c aJ aa 1X2683 which is the same result reported by Sarmento and Tucker [21] and more accurate than the mean-field theory result T c aJ aa 3. We now apply the obtained formalism to an alternating magnetic superlattice consisting of atoms of type A and B which alternate as F F F ABABA F F F AB F F F The periodic condition suggests that we only have to consider one unit cell which interacts with its nearest neighbors via the interlayer coupling.…”

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].…”
