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…
Self-assembly of magnetic iron oxide nanoparticles into cuboidal superstructures
Sabine Rosenfeldt, Stephan Förster, Thomas Friedrich +2
This chapter describes the synthesis and some characteristics of magnetic iron oxide nanoparticles, mainly nanocubes, and focus on their self-assembly into crystalline cuboids in d…
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…
A note on the magnetic spatial forcing of a ferrofluid layer
Thomas Friedrich, Adrian Lange, Ingo Rehberg +1
We report on the response of a thin layer of ferrofluid to a spatially modulated magnetic field. This field is generated by means of a constant current in a special arrangement of…
Magnetic traveling-stripe-forcing: enhanced transport in the advent of the Rosensweig instability
Thomas Friedrich, Ingo Rehberg, Reinhard Richter
A new kind of contactless pumping mechanism is realized in a layer of ferrofluid via a spatio-temporally modulated magnetic field. The resulting pressure gradient leads to a liquid…
