The intrinsic ferromagnetism of CoBr2 bulk was investigated using DFT (density functional theory) combined with the full potential linear augmented plane wave method and Monte Carlo simulations. The ground state of CoBr2 exhibits ferromagnetic behavior and a semiconductor character. We used the generalized gradient approximation (GGA) and GGA + U (Hubbard correction) approximations to determinate the magnetic moment. The magnetic moment reached the experimental value and was in good agreement… 
Ground-State Structures of the Ising Model on a Layered Triangular Lattice in a Magnetic Field
Abstract The magnetic structures of the ground state, as well as magnetic and thermodynamic properties of the antiferromagnetic Ising model on a layered lattice, are investigated based on the
The Impact of the Surface Modification on Tin-Doped Indium Oxide Nanocomposite Properties
An analysis of the theoretical methods to study the effects of surface modification on structural properties of nanostructured indium tin oxide (ITO) shows that the change in optoelectronic properties of the surface is mainly due to functionalizing the surface with organic molecules and that the electrocatalytic properties vary as a function of size.
