Resonant inelastic x-ray scattering of magnetic excitations under pressure
Matteo Rossi, Christian Henriquet, Jeroen Jacobs +15
Resonant inelastic x-ray scattering (RIXS) is an extremely valuable tool for the study of elementary, including magnetic, excitations in matter. Latest developments of this techniq…
The collapsed tetragonal phase as a strongly covalent and fully nonmagnetic state: persistent magnetism with interlayer As-As bond formation in Rh-doped CaSrFeAs
K. Zhao, J. K. Glasbrenner, H. Gretarsson +10
A well-known feature of CaFeAs-based superconductors is the pressure-induced collapsed tetragonal phase that is commonly ascribed to the formation of an interlayer As-A…
Direct bulk sensitive probe of 5f symmetry in URu2Si2
Martin Sundermann, Maurits W. Haverkort, Stefano Agrestini +8
The second-order phase transition into a hidden order phase in URuSi goes along with an order parameter which is still a mystery, despite 30 years of research. However, it…
Persistent paramagnons deep in the metallic phase of SrLaIrO
H. Gretarsson, N. H. Sung, J. Porras +13
We have studied the magnetic excitations of electron-doped SrLaIrO () using resonant inelastic x-ray scattering (RIXS) at the Ir L-edge. The…
CeRuSn: a strongly correlated material with nontrivial topology
M. Sundermann, F. Strigari, T. Willers +14
Topological insulators form a novel state of matter that provides new opportunities to create unique quantum phenomena. While the materials used so far are based on semiconductors,…
Evidence of quantum dimer excitations in SrIrO
M. Moretti Sala, V. Schnells, S. Boseggia +12
The magnetic excitation spectrum in the bilayer iridate SrIrO has been investigated using high-resolution resonant inelastic x-ray scattering (RIXS) performed at the ir…
Direct Evidence for Dominant Bond-directional Interactions in a Honeycomb Lattice Iridate Na2IrO3
Sae Hwan Chun, Jong-Woo Kim, Jungho Kim +15
Heisenberg interactions are ubiquitous in magnetic materials and have been prevailing in modeling and designing quantum magnets. Bond-directional interactions offer a novel alterna…
Role of Zinc and Niobium in the Giant Piezoelectric Response of PbZn1/3Nb2/3O3
Ali Al-Zein, Hichem Dammak, Philippe Papet +5
Relaxor ferroelectric perovskites are highly polarizable and can exhibit giant coupling between elastic strain and an applied electric field. Here, we report an in situ extended X-…
Crystal field splitting in SrIrO ( = 1, 2) iridates probed by x-ray Raman spectroscopy
M. Moretti Sala, M. Rossi, A. Al-Zein +9
Non-resonant Raman spectroscopy in the hard X-ray regime has been used to explore the electronic structure of the first two members of the Ruddlesden-Popper series SrIr…
CaIrO3: a Spin-Orbit Mott Insulator Beyond the jeff = 1/2 Ground State
M. Moretti Sala, K. Ohgushi, A. Al-Zein +3
In CaIrO3 electronic correlation, spin-orbit coupling, and tetragonal crystal field splitting are predicted to be of comparable strength. However, the nature of its ground state is…
