Combined funnel, concentrator, and particle valve functional element for magnetophoretic bead transport based on engineered magnetic domain patterns

Rico Huhnstock, Lukas Paetzold, Maximilian Merkel +2

Controlled actuation of superparamagnetic beads (SPBs) within a microfluidic environment using tailored dynamic magnetic field landscapes (MFLs) is a potent approach for the realiz…

Exploring energy landscapes of charge multipoles using constrained density functional theory

Luca Schaufelberger, Maximilian E. Merkel, Aria Mansouri Tehrani +2

We present a method to constrain local charge multipoles within density-functional theory. Such multipoles quantify the anisotropy of the local charge distribution around atomic si…

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…
