Thermodynamics of itinerant magnets in a classical spin fluctuation model
A. L. Wysocki, J. K. Glasbrenner, K. D. Belashchenko
Thermodynamics of itinerant magnets is studied using a classical model with one parameter characterizing the degree of itinerancy. Monte Carlo simulations for bcc and fcc lattices…
Magnetism of chromia
Siqi Shi, A. L. Wysocki, K. D. Belashchenko
The electronic structure and magnetism of chromia (corundum-type Cr2O3) are studied using full-potential first-principles calculations. The electronic correlations are included wit…
Role of covalent Fe-As bonding in the magnetic moment formation and exchange mechanisms in iron-pnictide superconductors
K. D. Belashchenko, V. P. Antropov
The electronic origin of the huge magnetostructural effect in layered Fe-As compounds is elucidated using LiFeAs as a prototype. The crucial feature of these materials is the stron…
