In earlier work, we previously established a formalism that allows to express the exchange energy J vs. fundamental molecular integrals without crystal field, for a fragment A–X–B, where A and B are 3d1 ions and X is a closed-shell diamagnetic li

We examine double chains of spins 1/2 with Ising-like nearest-neighbor interactions showing magnetic frustrations that we define. The critical temperature of such systems is T c = 0 K like for spin chains (1d systems). We recall the theoretical treat

We rigorously examine 2d-square lattices composed of classical spins isotropically coupled between first-nearest neighbours. A general expression of the characteristic polynomial associated with the zero-field partition function Zinf{N}(0) is establi

Magnetocrystalline anisotropy of iron borate is expected to have two contributions: the crystal field one and the dipole-dipole one. The crystal field contribution is calculated through the perturbation theory using the spin Hamiltonian parameters of

In this article, we exclusively focus on the low-temperature behaviors of 2d square lattices composed of (2N +1)2classical spins with isotropic couplings between first-nearest neighbors (Heisenberg couplings), in the thermodynamic limit (N +∞). Aft

The problem of direct exchange is examined in the simplest cases (formal coupling of two electrons initially isolated and hydrogen molecule). Then we consider the general case of a solid characterized by weak overlaps between the atomic orbitals of f

Magnetic circular dichroism and X-ray diffraction were used to investigate the structure and magnetooptical properties of nanoparticles formed in potassium-aluminum-germanium-boron glass doped with iron and rare-earth elements. It is demonstrated tha
