High-resolution resonant inelastic x-ray scattering study of the electron-phonon coupling in honeycomb -LiIrO
J. G. Vale, C. D. Dashwood, E. Paris +11
The excitations in honeycomb -LiIrO have been investigated with high-resolution resonant inelastic x-ray scattering (RIXS) at the O K edge. The low-energy response is do…
Possible quantum paramagnetism in compressed SrIrO
D. Haskel, G. Fabbris, J. H. Kim +9
The effect of compression on the magnetic ground state of SrIrO is studied with x-ray resonant techniques in the diamond anvil cell. The weak interlayer exchange coupling b…
Controlling Ferromagnetic Ground States and Solitons in Thin Films and Nanowires built from Iron Phthalocyanine Chains
Zhenlin Wu, Peter Robaschik, Luke R. Fleet +3
Iron phthalocyanine (FePc) is a molecular semiconductor whose building blocks are one-dimensional ferromagnetic chains. We show that its optical and magnetic properties are control…
Selective probing of magnetic order on Tb and Ir sites in stuffed TbIrO using resonant X-ray scattering
C. Donnerer, M. C. Rahn, E. Schierle +7
We study the magnetic structure of the "stuffed" (Tb-rich) pyrochlore iridate TbIrO, using resonant elastic x-ray scattering (REXS). In order to disentangle…
First principles soft mode lattice dynamics of PbZrTiO and shortcomings of the virtual crystal approximation
Jack S. Baker, David Bowler
A comparative study between PbTiO, PbZrO, and the solid solution PbZrTiO is performed on the soft mode lattice dynamics within the first Brillouin Zone.…
A linear combination of atomic orbitals (LCAO) model for deterministically placed acceptor arrays in silicon
Jianhua Zhu, Wei Wu, A. J. Fisher
We develop a tight-binding model based on linear combination of atomic orbitals (LCAO) methods to describe the electronic structure of arrays of acceptors, where the underlying bas…
