Current Research

  1. Magnetic and transport properties of heterostructures of nanoscale size.

a)     Transport properties of nanowires, nanocontacts, and ferroelectric (molecular) tunnel junctions.

b)     Transition metal clusters embedded in nonmagnetic matrix: magnetization, cluster-cluster interactions, anisotropy.

  1. Simulation of the growth of self-organized magnetic nanostructures. Modeling of the diffusion processes and growth on strained surfaces. Strain assisted phase segregation on the surface.
  2. Micromagnetic studies of nanostructured magnetic thin films.
  3. Surface properties of TM oxides (ZrO2, TiO2 etc.) Superhydrophilic/hydrophobic surfaces.
