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 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…
Control of Mooij correlations at the nanoscale in the disordered metallic Ta - nanoisland FeNi multilayers
N. N. Kovaleva, F. V. Kusmartsev, A. B. Mekhiya +12
Localisation phenomena in highly disordered metals close to the extreme conditions determined by the Mott-Ioffe-Regel (MIR) limit when the electron mean free path is approximately…
Spin-phonon interaction increased by compressive strain in antiferromagnetic MnO thin films
Alireza Kashir, Veronica Goian, Oliva Pacherova +3
MnO thin films with various thicknesses and strains were grown on MgO substrates by pulsed laser deposition, then characterized using x-ray diffraction and infrared reflectance spe…
Strong spin-phonon coupling in infrared and Raman spectra of SrMnO3
S. Kamba, V. Goian, V. Skoromets +9
Infrared reflectivity spectra of cubic SrMnO ceramics reveal 18 % stiffening of the lowest-frequency phonon below the antiferromagnetic phase transition occurring at T…
Antiferrodistortive phase transition in EuTiO3
V. Goian, S. Kamba, O. Pacherova +14
X-ray diffraction, dynamical mechanical analysis and infrared reflectivity studies revealed an antiferrodistortive phase transition in EuTiO3 ceramics. Near 300K the perovskite str…
