TL;DR: Band structure calculations indicate that Mg is substantially ionized, and the bands at the Fermi level derive mainly from B orbitals, and MgB2 can be viewed as an analog of the long sought, but still hypothetical, superconducting metallic hydrogen.

TL;DR: In this paper, density functional studies of the electronic structures and exchange interaction parameters have been performed for a series of ferromagnetic full Heusler alloys of general formula, and the connection between the electronic spectra and the magnetic interactions have been studied.

TL;DR: Neutron scattering measurements of the magnetic excitations in single crystals of antiferromagnetic CaFe2As2 reveal steeply dispersive and well-defined spin waves up to an energy of approximately 100 meV, suggesting that the high energy behavior is dominated by the damping of spin waves by particle-hole excitations.

TL;DR: In this article, the addition of a biquadratic interaction term to the usual Heisenberg Hamiltonian leads to a description of many experimental observations, such as magnetic properties of pnictide superconductors.

TL;DR: The electronic structure and numerous magnetic properties of MnBi magnetic systems are investigated using local spin density approximation with on-cite Coulomb correlations (LSDA+U) included in this article.
