Bretzel, S. (author)
Gyromagnetic experiments, the Barnett effect (magnetization by rotation) and the Einstein-de Haas effect (rotation by magnetization), were initially devised to test the molecular current hypothesis and determine the electron g-factor at the dawn of quantum mechanics. Advances in fabrication techniques and an ever increasing control of materials...

We present the linear-response matrix for a sliding domain wall in a rotatable magnetic nanowire, which is driven out of equilibrium by temperature and voltage bias, mechanical torque, and magnetic field. An expression for heat-current-induced domain-wall motion is derived. Application of Onsager’s reciprocity relation leads to a unified...

The Barnett effect refers to the magnetization induced by rotation of a demagnetized ferromagnet. We describe the location and stability of stationary states in rotating nanostructures using the Landau–Lifshitz–Gilbert equation. The conditions for an experimental observation of the Barnett effect in different materials and sample geometries are...
