Magnetoelastic hybrid excitations in CeAuAl
Petr Čermák, Astrid Schneidewind, Benqiong Liu +5
The interactions between elementary excitations such as phonons, plasmons, magnons, or particle-hole pairs, drive emergent functionalities and electronic instabilities such as mult…
Lattice dynamics and coupled quadrupole-phonon excitations in CeAuAl
B. -Q. Liu, P. Čermák, C. Franz +2
We report first principles calculations of the structural parameters and phonon dispersion of the tetragonal non-centrosymmetric heavy fermion compound CeAuAl. Taking into acco…
Local atomic arrangement in LaCuAl3 and LaAuAl3 by NMR and density functional theory
Vojtech Chlan, Petr Dolezal, Rachel Sgallova +2
CeCuAl3 and CeAuAl3, crystallizing in the non-centrosymmetric BaNiSn3 tetragonal structure, are known mainly for their unusual neutron scattering spectra involving additional excit…
Ultra-High Resolution Neutron Spectroscopy of Low-Energy Spin Dynamics in UGe
F. Haslbeck, S. Säubert, M. Seifert +9
Studying the prototypical ferromagnetic superconductor UGe we demonstrate the potential of the Modulated IntEnsity by Zero Effort (MIEZE) technique---a novel neutron spectrosco…
