Tunable dynamics of flexible magnetic microcrosses: synchronous rotation, breathing and out-of-plane arm overtaking
Joseph Tavacoli, Andris P. Stikuts, Mihir Dass +2
We combine colloidal self-assembly and soft-lithography techniques to realize flexible magnetic microcrosses that can be manipulated via external, time dependent magnetic fields. T…
Engineering tunable fractional Shapiro steps in colloidal transport
Andris P. Stikuts, Seemant Mishra, Artem Ryabov +2
Shapiro steps are quantized plateaus in the velocity-force or velocity-torque curve of a driven system, when its speed remains constant despite an increase in the driving force. Fo…
Macroscopic emulation of microscopic magnetic particle systems
Viesturs Spūlis, Daniels Gorovojs, Jānis Pudāns +5
In this work we show that macroscopic experiments can be used to investigate microscopic systems. Such macroscopic experiments enable testing the assumptions and results obtained b…
Ferromagnetic filament shapes in a rotating field reveal their magnetoelastic properties
Andris P. Stikuts, Andrejs Cēbers, Guntars Kitenbergs
Flexible ferromagnetic filaments can be used to control the flow on the micro-scale with external magnetic field. To accurately model them, it is crucial to know their parameters s…
Spontaneous order in ensembles of rotating magnetic droplets
Andris P. Stikuts, Régine Perzynski, Andrejs Cēbers
Ensembles of elongated magnetic droplets in a rotating field are studied experimentally. In a given range of field strength and frequency the droplets form rotating structures with…
