CaCuRuO: a high Kondo-temperature transition metal oxide
D. Takegami, C. Y. Kuo, K. Kasebayashi +26
We present a comprehensive study of CaCuRuO using bulk sensitive hard and soft x-ray spectroscopy combined with local-density approximation (LDA) + dynamical mean-fi…
On the multiferroic skyrmion-host GaV4S8
S. Widmann, E. Ruff, A. Günther +6
The lacunar spinel GaV4S8 exhibits orbital ordering at 44 K and shows a complex magnetic phase diagram below 12.7 K, which includes ferromagnetic and cycloidal spin order. At low b…
Magnetism of PdNi alloys near the critical concentration for ferromagnetism
G. M. Kalvius, O. Hartmann, R. Wäppling +11
We report results of a muon spin rotation and relaxation (SR) study of dilute PdNi alloys, with emphasis on Ni concentrations 0.0243 and 0.025. These are close…
FeCrS in magnetic fields: possible evidence for a multiferroic ground state
J. Bertinshaw, C. Ulrich, A. Günther +11
We report on neutron diffraction, thermal expansion, magnetostriction, dielectric, and specific heat measurements on polycrystalline FeCr2S4 in external magnetic fields. The ferrim…
Correlation effects in CaCu3Ru4O12
N. Hollmann, Z. Hu, A. Maignan +7
We have investigated the electronic structure of CaCu3Ru4O12 and LaCu3Ru4O12 using soft x-ray photoelectron and absorption spectroscopy together with band structure and cluster con…
Magnetic ground state and 2D behavior in pseudo-Kagome layered system Cu3Bi(SeO3)2O2Br
M. Pregelj, O. Zaharko, A. Günther +3
Anisotropic magnetic properties of a layered kagome-like system Cu3Bi(SeO3)2O2Br have been studied by bulk magnetization and magnetic susceptibility measurements as well as powder…
Magnetization and specific heat of the dimer system CuTe2O5
R. M. Eremina, T. P. Gavrilova, A. Günther +7
We report on magnetization and specific heat measurements on single-crystalline CuTe2O5. The experimental data are directly compared to theoretical results for two different spin s…
Optical study of phonons and electronic excitations in tetragonal SrVO
J. Teyssier, R. Viennois, E. Giannini +5
We report on the optical excitation spectra in SrVO. The phonon modes are assigned and their evolution with temperature is discussed in the frame of the different phase tra…
Orbital fluctuations and orbital order below the Jahn-Teller transition in Sr3Cr2O8
Zhe Wang, M. Schmidt, A. Günther +10
We report on the magnetic and phononic excitation spectrum of Sr3Cr2O8 determined by THz and infrared (IR) spectroscopy, and electron spin resonance (ESR) measurements across the J…
