Coexistence of Superconductivity and Magnetism in FeSe_1-x under Pressure
M. Bendele, A. Ichsanow, Yu. Pashkevich +7
An extended investigation of the electronic phase diagram of FeSe up to pressures of \,GPa by means of ac and dc magnetization, zero field muon spin rotation (Z…
Magnetic Dynamics and Spin Freezing in the Ferromagnetic Phase of Ba-Doped Perovskite Cobaltites
M. Stingaciu, H. Luetkens, Y. G. Pashkevich +3
The magnetic properties of polycrystaline La0.5Ba0.5CoO2.5+d (d = 0.44 and 0.485) where investigated using muon spin relaxation and bulk magnetization experiments. Below a Curie te…
Helical fluctuations in the Raman response of the topological insulator Bi2Se3
V. Gnezdilov, Yu. G. Pashkevich, H. Berger +3
The topological insulator Bi2Se3 shows a Raman scattering response related to topologically protected surface states amplified by a resonant interband transition. Most significantl…
Anomalous optical phonons in FeTe pnictides: spin state, magnetic order, and lattice anharmonicity
V. Gnezdilov, Yu. Pashkevich, P. Lemmens +8
Polarized Raman-scattering spectra of non-superconducting, single-crystalline FeTe are investigated as function of temperature. We have found a relation between the magnitude of or…
