To succeed in the next generation of magnetic storages, nanomagnetic structures must be engineered to allow modulation of magnetization amplitude and spatial period. We demonstrate computationally how magnetic nanostructures states (domains with narr

Bismuth (Bi) having a large atomic number is characterized by the strong spin-orbit coupling (SOC) and is a parent compound of many 3D topological insulators (TIs). The ultrathin Bi films are supposed to be 2D TIs possessing the nontrivial topology,

Using wide-band (0.5-6.5 eV) spectroscopic ellipsometry we study ultrathin [Bi(0.6-2.5 nm)-FeNi(0.8,1.2 nm)]N multilayer films grown by rf sputtering deposition, where the FeNi layer has a nanoisland structure and its morphology and magnetic properti

The complex index of refraction in the spectral range of 0.74 to 4.5 eV is studied by variable-angle spectroscopic ellipsometry in ferroelectric K0.5Na0.5NbO3 films. The 20-nm-thick cube-on-cube-type epitaxial films are grown on SrTiO3(001) and DyScO

Using dc transport and wide-band spectroscopic ellipsometry techniques we study localization phenomena in highly disordered metallic \beta-Ta films grown by rf sputtering deposition. The dc transport study implies non-metallic behavior (dr/dT<0), wit

Using dc transport and wide-band spectroscopic ellipsometry techniques, we study localization effects in the disordered metallic Ta interlayer of different thickness in the multilayer films (MLFs) (Ta - FeNi)_N grown by rf sputtering deposition. In t

Very large lattice strain and strain-induced polarization are achieved in KNbO _3 using epitaxial growth of a thin KNbO _3 film onto a (001)-oriented SrTiO _3 single-crystal substrate. We demonstrate experimentally that epitaxy produces dramatic chan
