Shape transitions of giant liposomes induced by an anisotropic spontaneous curvature
O. Sandre, Christine Ménager, J. Prost +3
We explore how a magnetic field breaks the symmetry of an initially spherical giant liposome filled with a magnetic colloid. The condition of rotational symmetry along the field ax…
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…
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…
Orientational Dynamics of Fluctuating Dipolar Particles Assembled in a Mesoscopic Colloidal Ribbon
Helena Massana-Cid, Fernando Martinez-Pedrero, Andrejs Cebers +1
We combine experiments and theory to investigate the dynamics and orientational fluctuations of ferromagnetic microellipsoids that form a ribbon-like structure due to attractive di…
