Lattice dynamics and spin excitations in the metal-organic framework [CHNH][Co(HCOO)]
Lei Ding, Claire V. Colin, Virginie Simonet +11
In metal-organic-framework (MOF) perovskites, both magnetic and ferroelectric orderings can be readily realized by compounding spin and charge degrees of freedom. The hydrogen bond…
Large dynamic scissoring mode displacements coupled to band gap opening in Hybrid Perovskites
Tobias A. Bird, Jungshen Chen, Manila Songvilay +4
Hybrid perovskites are a rapidly growing research area, having reached photovoltaic power conversion efficiencies of over 25 \%. We apply a symmetry-motivated analysis method to an…
Broadband critical dynamics in disordered lead-based perovskites
C. Stock, M. Songvilay, P. M. Gehring +2
Materials based on the cubic perovskite unit cell continue to provide the basis for technologically important materials with two notable recent examples being lead-based relaxor pi…
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…
