(2013-01-11)
Noncollinear spins are among the most interesting features of magnetic materials, and their accurate description is a central goal of density functional theory applied to periodic solids. However, these calculations typically ...
• #### Numerical calculation of interaction forces between paramagnetic colloids in two-dimensional systems ﻿

(2014)
Typically the force between paramagnetic particles in a uniform magnetic field is described using the dipolar model, which is inaccurate when particles are in close proximity to each other. Instead, the exact force between ...
