Tuning properties of phase-separated magnetic fluid with temperature
Laura Nelsone, Guntars Kitenbergs
Phase-separated magnetic fluids provide a very strong magnetic response () in a liquid state material. Even small fields can cause a notable material response, but this depen…
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…
Swarming of micron-sized hematite cubes in a rotating magnetic field -- Experiments
Oksana Petrichenko, Guntars Kitenbergs, Martins Brics +3
Energy input by under-field rotation of particles drives the systems to emergent non-equilibrium states. Here we investigate the suspension of rotating magnetic cubes. Micron-sized…
Rivalry of diffusion, external field and gravity in micro-convection of magnetic colloids
Guntars Kitenbergs, Andrejs Cēbers
Magnetic fields and magnetic materials have promising microfluidic applications. For example, magnetic micro-convection can enhance mixing considerably. However, previous studies h…
Deformation of flexible ferromagnetic filaments under a rotating magnetic field
Abdelqader Zaben, Guntars Kitenbergs, Andrejs Cēbers
Research on magnetic particles dispersed in a fluid medium, actuated by a rotating magnetic field, is becoming increasingly active for both lab-on-chip and bio-sensing applications…
