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…
Rolling ferrofluid drop on the surface of a liquid
V. Sterr, R. Krauss, K. I. Morozov +3
We report on the controlled transport of drops of magnetic liquid, which are swimming on top of a non-magnetic liquid layer. A magnetic field which is rotating in a vertical plane…
Response of a ferrofluid to traveling-stripe forcing
A. Beetz, C. Gollwitzer, R. Richter +1
We observe the dynamics of waves propagating on the surface of a ferrofluid under the influence of a spatially and temporarily modulated field. In particular, we excite plane waves…
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…
