He obtained his Candidate Dissertation in Physics and Mathematics in 1985 from Donetsk National University under the supervision of Volodymyr Semynozhenko, “On the theory of the normal and ferromagnetic superconductors in the strong electromagnetic fields”.
He discovered the phenomenon while designing a ferromagnetic surface layer to the magnetic drum memory for the BESK computer.
Magnetic tweezers, a trap using a magnetic field to trap micrometre-seized ferromagnetic beads
The presence of strongly magnetic ions or particles (e.g. ferromagnetic, paramagnetic) also strongly alter T1 values and are widely used as MRI contrast agents.
B. A. Finlayson first explained in 1970 (in his paper "Convective instability of ferromagnetic fluids", Journal of Fluid Mechanics 40:753-767) how an external magnetic field imposed on a ferrofluid with varying magnetic susceptibility, e.g., due to a temperature gradient, results in a nonuniform magnetic body force, which leads to thermomagnetic convection.
