Topological sorting of magnetic colloidal bipeds
Aneena Rinu Perayil, Piotr KuÅwik, Maciej Urbaniak +5
Topologically nontrivial adiabatic loops of the orientation of a homogeneous external magnetic field drive the walking of paramagnetic colloidal bipeds above a deformed quasi-perio…
Topologically cloaked magnetic colloidal transport
Anna M. E. B. Rossi, Thomas Märker, Nex C. X. Stuhlmüller +8
Cloaking is a method of making obstacles undetectable. Here we cloak unit cells of a magnetic pattern squeezed into an otherwise periodic pattern from a magnetically driven colloid…
Origin of ion bombardment induced Tb oxidation in Tb/Co multilayers
Daniel Kiphart, Michal Krupinski, Marzena Mitura-Nowak +6
Ion bombardment is currently an active area of research for patterning rare earth/transition metal ferrimagnetic thin films because the magnetic properties are extremely sensitive…
Magnetic colloidal single particles and dumbbells on a tilted washboard moire pattern in a precessing external field
Farzaneh Farrokhzad, Nex C. X. Stuhlmüller, Piotr KuÅwik +6
We measure the dynamical behavior of colloidal singlets and dumbbells on an inclined magnetic moiré pattern, subject to a precessing external homogeneous magnetic field. At low ex…
Spin wave frequency hysteresis in Ir/Co/Pt multilayers with Dzyaloshinskii-Moriya interaction
Ryszard Gieniusz, Pawel Gruszecki, Jan Kisielewski +9
Results of extensive combined experimental and theoretical investigations on static and dynamic properties of Ir/Co/Pt multilayer with low uniaxial anisotropy and asymmetric Ir/Co…
Topologically controlled synthesis of active colloidal bipeds
Jonas Elschner, Farzaneh Farrokhzad, Piotr KuÅwik +6
Topological growth control allows to produce a narrow distribution of outgrown colloidal rods with defined and adjustable length. We use an external magnetic field to assemble para…
