Surface Instabilities and Magnetic Soft Matter
Christian Gollwitzer, Marina Krekhova, Guenter Lattermann +2
We report on the formation of surface instabilities in a layer of thermoreversible ferrogel when exposed to a vertical magnetic field. Both static and time dependent magnetic field…
Measuring the deformation of a ferrogel sphere in a homogeneous magnetic field
Christian Gollwitzer, Alexander Turanov, Marina Krekhova +3
A sphere of a ferrogel is exposed to a homogeneous magnetic field. In accordance to theoretical predictions, it gets elongated along the field lines. The time-dependence of the ela…
Via Hexagons to Squares in Ferrofluids: Experiments on Hysteretic Surface Transformations under Variation of the Normal Magnetic Field
Christian Gollwitzer, Ingo Rehberg, Reinhard Richter
We report on different surface patterns on magnetic liquids following the Rosensweig instability. We compare the bifurcation from the flat surface to a hexagonal array of spikes wi…
