Decoupled molecular and inorganic framework dynamics in CHNHPbCl
M. Songvilay, Zitian Wang, V. Garcia Sakai +7
The organic-inorganic lead halide perovskites are composed of organic molecules imbedded in an inorganic framework. The compounds with general formula CHNHPbX (MA…
Spin-wave directional anisotropies in antiferromagnetic BaNbFeSiO
C. Stock, R. D. Johnson, N. Giles-Donovan +14
BaNbFeSiO (langasite) is structurally and magnetically single domain chiral with the magnetic helicity induced through competing symmetric exchange interac…
Common acoustic phonon lifetimes in inorganic and hybrid lead halide perovskites
M. Songvilay, N. Giles-Donovan, M. Bari +12
The acoustic phonons in the organic-inorganic lead halide perovskites have been reported to have anomalously short lifetimes over a large part of the Brillouin zone. The resulting…
Spin-Orbit Excitons in CoO
P. M. Sarte, M. Songvilay, E. Pachoud +10
CoO has an odd number of electrons in its unit cell, and therefore is expected to be metallic. Yet, CoO is strongly insulating owing to significant electronic correlations, thus cl…
Relaxing Kondo screened Kramers-doublets in CeRhSi
J. Pásztorová, A. Howell, M. Songvilay +10
CeRhSi is a superconductor under pressure coexisting with a weakly antiferromagnetic phase characterized by a Bragg peak at =( 0.2, 0, 0.5) (N. Aso et al.…
