Evidence for local lattice distortions in giant magnetocapacitive CdCr2S4
V. Gnezdilov, P. Lemmens, Yu. G. Pashkevich +6
Raman scattering experiments on CdCr2S4 single crystals show pronounced anomalies in intensity and frequency of optical phonon modes with an onset temperature T*=130 K that coincid…

Spectral sensitive phonon wipeout due to a fluctuating spin state in a Fe2+ coordination polymer
V. Gnezdilov, P. Lemmens, P. Scheib +7
Raman scattering in the spin-crossover system [Fe(pmd)(H2O){Au(CN)2}2]*H2O reveals a complex three-phase spin-state transition in contrast to earlier observations in magnetization…

Comment on "Raman spectroscopy study of NaxCoO2 and superconducting NaxCoO2 yH2O"
P. Lemmens, P. Scheib, Y. Krockenberger +5
The effect of surface degradation of the thermolectric cobaltite on Raman spectra is discussed and compared to experimental results from Co3O4 single crystals. We conclude that on…
