Bi layer properties in the Bi-FeNi GMR-type structures probed by spectroscopic ellipsometry
Natalia Kovaleva, Dagmar Chvostova, Ladislav Fekete +1
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 B…
Bismuth layer properties in the ultrathin Bi-FeNi multilayer films probed by spectroscopic ellipsometry
N. N. Kovaleva, D. Chvostova, O. Pacherova +6
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 lay…
Localization Phenomena in Disordered Tantalum Films
Natalia Kovaleva, Dagmar Chvostova, A. Dejneka
Using dc transport and wide-band spectroscopic ellipsometry techniques we study localization phenomena in highly disordered metallic β-Ta films grown by rf sputtering deposition. T…
Localization effects in the disordered Ta interlayer of multilayer Ta-FeNi films: Evidence from dc transport and spectroscopic ellipsometry study
N. N. Kovaleva, D. Chvostova, O. Pacherova +4
Using dc transport and wide-band spectroscopic ellipsometry techniques, we study localization effects in the disordered metallic Ta interlayer of different thickness in the multila…
Electron spin dynamics of Ce ions in YAG crystals studied by pulse-EPR and pump-probe Faraday rotation
D. V. Azamat, V. V. Belykh, D. R. Yakovlev +6
The spin relaxation dynamics of Ce ions in heavily cerium-doped YAG crystals is studied using pulse-electron paramagnetic resonance and time-resolved pump-probe Faraday rota…
Optical evidence of quantum rotor orbital excitations in orthorhombic manganites
N. N. Kovaleva, K. I. Kugel, Z. Potucek +8
In magnetic compounds with Jahn-Teller (JT) ions (such as Mn3+ or Cu2+), the ordering of the electron or hole orbitals is associated with cooperative lattice distortions. There the…
