Temperature controlled motion of an antiferromagnet-ferromagnet interface within a dopant-graded FeRh epilayer
C. Le Graët, T. R. Charlton, M. McLaren +7
Chemically ordered B2 FeRh exhibits a remarkable antiferromagnetic-ferromagnetic phase transition that is first order. It thus shows phase coexistence, usually by proceeding though…
Calculating electron momentum densities and Compton profiles using the linear tetrahedron method
D. Ernsting, D. Billington, T. D . Haynes +6
A method for computing electron momentum densities and Compton profiles from ab initio calculations is presented. Reciprocal space is divided into optimally-shaped tetrahedra for i…
Possible coupling between magnons and phonons in multiferroic CaMn7O12
Filip Kadlec, Veronica Goian, Christelle Kadlec +7
Spin and lattice dynamics of CaMn7O12 ceramics were investigated using infrared, THz and inelastic neutron scattering (INS) spectroscopies in the temperature range 2 to 590 K, and,…
Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator
C. Cacho, A. Crepaldi, M. Battiato +16
The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topol…
Population Inversion in Monolayer and Bilayer Graphene
Isabella Gierz, Matteo Mitrano, Jesse C. Petersen +7
The recent demonstration of saturable absorption and negative optical conductivity in the Terahertz range in graphene has opened up new opportunities for optoelectronic application…
The Ag...Ag dispersive interaction and exotic physical properties of Ag3Co(CN)6
Hong Fang, Martin T. Dove, Keith Refson
We report a density functional theory (DFT) study of Ag3Co(CN)6, a material noted for its colossal positive and negative thermal expansion, and its giant negative linear compressib…
