Three-dimensional close-to-substrate trajectories of magnetic microparticles in dynamically changing magnetic field landscapes
Rico Huhnstock, Meike Reginka, Claudius Sonntag +5
The transport of magnetic nano- or microparticles in microfluidic devices using artificially designed magnetic field landscapes (MFL) is promising for the implementation of key fun…
Polycrystalline exchange-biased bilayers: magnetically effective vs. structural antiferromagnetic grain volume distribution
Maximilian Merkel, Meike Reginka, Rico Huhnstock +1
The magnetic characteristics of polycrystalline exchange-biased antiferromagnet/ferromagnet-bilayers are determined by a complex interplay of parameters, describing structural and…
Magnetic hysteresis of individual Janus particles with hemispherical exchange-biased caps
S. Philipp, B. Gross, M. Reginka +5
We use sensitive dynamic cantilever magnetometry to measure the magnetic hysteresis of individual magnetic Janus particles. These particles consist of hemispherical caps of magneti…
Translatory and rotatory motion of Exchange-Bias capped Janus particles controlled by dynamic magnetic field landscapes
Rico Huhnstock, Meike Reginka, Andreea Tomita +6
Magnetic Janus particles (MJPs), fabricated by covering a non-magnetic spherical particle with a hemispherical magnetic in-plane exchange-bias layer system cap, display an onion ma…
Transport efficiency of biofunctionalized magnetic particles tailored by surfactant concentration
Meike Reginka, Hai Hoang, Özge Efendi +8
Controlled transport of surface functionalized magnetic beads in a liquid medium is a central requirement for the handling of captured biomolecular targets in microfluidic lab-on-c…
Simultaneous polydirectional transport of colloidal bipeds
Mahla Mirzaee-Kakhki, Adrian Ernst, Daniel de las Heras +6
Detailed control over the motion of colloidal particles is relevant in many applications in colloidal science such as lab-on-a-chip devices. Here, we use an external magnetic field…
Colloidal trains
Mahla Mirzaee-Kakhki, Adrian Ernst, Daniel de las Heras +10
Single and double paramagnetic colloidal particles are placed above a magnetic square pattern and are driven with an external magnetic field precessing around a high symmetry direc…
Magnetic domains without domain walls: a unique effect of He+ ion bombardment in ferrimagnetic Co/Tb multilayers
Łukasz Frąckowiak, Piotr Kuświk, Gabriel David Chaves-O'Flynn +6
We show that it is possible to engineer magnetic multi-domain configurations without domain walls in a prototypical rare earth/transition metal ferrimagnet using keV He+ ion bombar…
