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 fields are employed. Under variations of temperature, the viscoelastic properties of our soft magnetic matter can be tuned. Stress relaxation experiments unveil a stretched exponential scaling of the shear modulus, with an exponent of β = 1/3. The resulting magnetic threshold for the formation of Rosensweig-cusps is… Expand
Surface Instabilities of Ferrofluids
We report on recent progress in understanding the formation of surface protuberances on a planar layer of ferrofluid in a magnetic field oriented normally to the surface. This normal field orExpand
Meniscus of a ferrofluid around a vertical cylindrical wire carrying electric current.
TLDR
The classical model that neglects interface tension yields significant deviations from the experimental profiles in the parameter range studied, which can be modeled by the equilibrium of magnetic, gravitational, and interface tension forces. Expand
Retarding the growth of the Rosensweig instability unveils a new scaling regime.
Using a highly viscous magnetic fluid, the dynamics in the aftermath of the Rosensweig instability can be slowed down by more than 2000 times. In this way we expand the regime where the growth rateExpand

The role of structural anisotropy in the magnetooptical response of an organoferrogel with mobile magnetic nanoparticles.
TLDR
It is demonstrated that the presence of the gel network restricts the magnetooptical response of the ferrogel, and the optical response in structurally anisotropic gels becomes orientation-dependent, revealing an intricate interplay between the gel mesh and the MNPs. Expand
