The treatment of Heisenberg films with many-body Green's function theory (GFT) is
reviewed. The basic equations of GFT are derived in sufficient detail so that the rest of the …

High-quality antiferromagnetic (AF) superlattices (FeF 2) m (CoF 2) n, as judged from high-
resolution x-ray diffraction (HRXD), were grown on (001) ZnF 2 substrates. Using HRXD, the …

In this review, we trace the evolution of the quantum spin-wave theory treating non-collinear
spin configurations. Non-collinear spin configurations are consequences of the frustration …

Quantum effects on surface magnetizations in antiferromagnetic thin films with Heisenberg
spins (S= 1/2) are investigated in detail theoretically. The system studied is a film with a body …

Using neutron diffraction, x-ray scattering, and bulk-magnetization methods, we have
characterized the magnetic structure for Fe 3 O 4/NiO superlattices grown by molecular …

The spin-wave spectrum of infinite, semi-infinite, and finite ferromagnetic superlattices with
arbitrary elementary units is analyzed theoretically in the exchange-dominated region. The …

We study properties of a helimagnetic thin film with a quantum Heisenberg spin model by
using the Green's-function method. Surface spin configuration is calculated by minimizing …

We study the critical behavior of magnetic thin films as a function of the film thickness. We
use the ferromagnetic Ising model with the high-resolution multiple histogram Monte Carlo …

Using a Green-function method the spin-wave excitation spectrum and the sublattice
magnetizations of a system consisting of a ferro-and an antiferromagnetic layer are …

In this study, we employ Monte Carlo simulations to explore the magnetic characteristics of a
double-cubic spin-½ and spin-1 ferromagnetic Ising superlattice system, focusing on the …
