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…

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…
