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…
Local flow measurements around flexible filaments under rotating magnetic field
Andris P. Stikuts, Abdelqader Zaben, Ivars Driķis +4
Effective mixing of fluids at the microfluidic scale is important for future applications in biology, medicine, and chemistry. A promising type of micromixers are magnetic filament…
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…
A 3D BEM algorithm for simulations of magnetic fluid droplet dynamics
Aigars Langins, Andris P. Stikuts, Andrejs Cēbers
This paper outlines a numerical algorithm that could be used for simulating full 3D dynamics of magnetic fluid droplet shapes in external magnetic fields, by solving boundary integ…
Small deformation theory for a magnetic droplet in a rotating field
Andris P. Stikuts, Régine Perzynski, Andrejs Cēbers
A three dimensional small deformation theory is developed to examine the motion of a magnetic droplet in a uniform rotating magnetic field. The equations describing the droplet's 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…
