Magnetic Phases

The magnetic susceptibility measurements have been made on antiferromagnetic compounds Mn1–xFexSn2 and the magnetic phase diagram was illustrated. The high temperature magnetic phases I and III, major phases, were analyzed on the basis of molecular field theory and explained the change of magnetic structure I⇌III occured at x≈0.8.

Model Relation

We consider the magnetic phase diagram of the two-dimensional Hubbard model ona square lattice.We take into account both spiral and collinear incommensurate magnetic states.The possibility of phase separation of spiral magnetic phases is taken into consideration as well.Our study shows that all the listed phases appear to be the ground state at certain parametersof the model. Relation of the obtained results to real materials, e.g. Cu-based high-temperaturesuperconductors, is discussed.

Good Agreement

Using Perdew–Burke–Ernzerhof [Formula: see text] formalism, we present a systematic study of the magnetic phase stability, mechanical properties, electronic density of states and band gaps of actinide dioxides ([Formula: see text]). Relativistic effects are also considered via the spin orbit coupling. The [Formula: see text] electrons behavior has been investigated as a function of the Coulomb repulsion [Formula: see text]. Lattice parameters, elastic constants and band gaps of [Formula: see text] are consistently in good agreement with the available experimental data. From [Formula: see text] calculations, all [Formula: see text] are found to be semiconductors or insulators. Our results show that the strong correlation treatment by the Coulomb potential and the spin orbit interactions are necessary to predict the accurate electronic structure of this series of materials.
