Heisenberg fluids under confinement — •Stefanie Maria Wandrei1, Roland Roth2, and Martin Schoen1 — 1Technische Universität Berlin — 2Eberhard Karls Universität Tübingen
In this work we employ classical density functional theory (DFT) to investigate the behavior of a Heisenberg fluid at a single wall or confined to a nanoscopic slit pore of variable width. We consider three different types of confining surfaces: hard walls, simple attractive walls, and attractive walls with an additional field acting on the spins. To account for the locality of the density we use the White Bear version of fundamental measure theory. This allows us to investigate in greater detail than in previous works the effect that competing external fields have on the behavior of the confined fluid.
