Unknotting of quasi-two-dimensional ferrogranular networks by in-plane homogeneous magnetic fields
Pedro A. Sánchez, Justus Miller, Sofia S. Kantorovich +1
Our ongoing research addresses, by means of experiments and computer simulations, the aggregation process that takes place in a shaken granular mixture of glass and magnetized stee…
Measuring magnetic moments of polydisperse ferrofluids utilizing the inverse Langevin function
Ingo Rehberg, Reinhard Richter, Stefan Hartung +3
The dipole strength of magnetic particles in a suspension is obtained by a graphical rectification of the magnetization curves based on the inverse Langevin function. The method yi…
Graphical Magnetogranulometry of EMG909
Ingo Rehberg, Reinhard Richter, Stefan Hartung
The magnetization curve of the ferrofluid EMG909 is measured. It can adequately be described by a superposition of four Langevin terms. The effective dipole strength of the magneti…
Retarding the growth of the {Rosensweig} instability unveils a new scaling regime
Adrian Lange, Christian Gollwitzer, Robin Maretzki +2
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 wher…
Homoclinic snaking near the surface instability of a polarizable fluid
David J. B. Lloyd, Christian Gollwitzer, Ingo Rehberg +1
We report on localized patches of cellular hexagons observed on the surface of a magnetic fluid in a vertical magnetic field. These patches are spontaneously generated by jumping i…
Spherical sample holders to improve the susceptibility measurement of superparamagnetic materials
Thomas Friedrich, Tobias Lang, Ingo Rehberg +1
The design of two custom sample holders with a spherical cavity for commercial vibrating sample magnetometer systems is described. For such cavities the magnetization M and the int…
