Rotating hematite cube chains
2023
Recently a two-dimensional chiral fluid was experimentally demonstrated. It was obtained from cubic-shaped hematite colloidal particles placed in a rotating magnetic field. Here we look at building blocks of that fluid, by analyzing short hematite chain behavior in a rotating magnetic field. We find equilibrium structures of chains in static magnetic fields and observe chain dynamics in rotating magnetic fields. We find and experimentally verify that there are three planar motion regimes and one where the cube chain goes out of the plane of the rotating magnetic field. In this regime we observe interesting dynamics -- the chain rotates slower than the rotating magnetic field. In order to ca…
Latvian-Brazilian meeting on Active and Soft Matter Physics: Book of Abstracts, Thursday, 3 February 2022, 15:00, Online
2022
This abstract book is made for the Latvian-Brazilian meeting on Active and Soft Matter Physics, held on February 3, 2022. It was organized by the MMML lab (Lab of Magnetic Soft Materials) of the University of Latvia together with the Condensed Matter Physics Group of the Federal University of Ceará (Fortaleza, Brazil) as a part of the 80th International Scientific Conference of the University of Latvia. It includes topical contributions from researchers working on active and soft matter physics at both research groups.
