Phonons reflect dynamic spin-state order in LaCoO
Alsu Ivashko, Taishun Manjo, Maximilian Kauth +17
We investigate lattice dynamics in LaCoO using inelastic neutron and x-ray scattering over $T = 2\mbox{-}650\,\mathrm{K}$, spanning the spin-state crossover at $T_{1} \approx 1…
Soft phonon and the central peak at the cubic-to-tetragonal phase transition in SrTiO
Avishek Maity, Klaus Habicht, Michael Merz +8
The continuous displacive phase transition in SrTiO near K features a central elastic peak in neutron scattering investigations at temperatures above , i…
Charge-density-wave quantum critical point under pressure in 2-TaSe
Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13
Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
Dominant in-plane symmetric elastoresistance in CsFe2As2
P. Wiecki, A. -A. Haghighirad, F. Weber +3
We study the elastoresistance of the highly correlated material CsFe2As2 in all symmetry channels. Neutralizing its thermal expansion by means of a piezoelectric-based strain cell…
Polaronic correlations and phonon renormalization in La1-xSrxMnO3 (x = 0.2, 0.3)
M. Maschek, J. -P. Castellan, D. Lamago +2
According to standard theory the magnetoresistance magnitude in ferromagnetic manganites crucially depends on the electron-phonon coupling strength. We showed that in La0.7Sr0.3MnO…
Magnetic and structural quantum phase transitions in CeCu6-xAux are independent
K. Grube, L. Pintschovius, F. Weber +9
The heavy-fermion compound CeCuAu has become a model system for unconventional magnetic quantum criticality. For small Au concentrations , the compound…
