The nature of Ho magnetism in multiferroic HoMnO3
S. Nandi, A. Kreyssig, L. Tan +6
Using x-ray resonant magnetic scattering and x-ray magnetic circular dichroism, techniques that are element specific, we have elucidated the role of Ho3+ in multiferroic HoMnO3. In…
Complex pressure-temperature structural phase diagram of honeycomb iridate CuIrO
G. Fabbris, A. Thorn, W. Bi +8
is among the newest layered honeycomb iridates and a promising candidate to harbor a Kitaev quantum spin liquid state. Here, we investigate the pressure and te…
Pressure-induced structural dimerization in the hyperhoneycomb iridate -LiIrO at low temperatures
L. S. I. Veiga, K. Glazyrin, G. Fabbris +10
A pressure-induced collapse of magnetic ordering in -LiIrO at GPa has previously been interpreted as evidence for possible emergence of spin liquid stat…
Synchrotron x-ray spectroscopy studies of valence and magnetic state in europium metal to extreme pressures
W. Bi, N. M. Souza-Neto, D. Haskel +9
In order to probe the changes in the valence state and magnetic properties of Eu metal under extreme pressure, x-ray absorption near-edge spectroscopy, x-ray magnetic circular dich…
Spin-orbit driven magnetic insulating state with character in a 4d oxide
S. Calder, L. Li, S. Okamoto +4
The unusual magnetic and electronic ground states of 5d iridates has been shown to be driven by intrinsically enhanced spin-orbit coupling (SOC). The influence of appreciable but r…
Electronic and structural ground state of heavy alkali metals at high pressure
G. Fabbris, J. Lim, L. S. I. Veiga +2
Alkali metals display unexpected properties at high pressure, including emergence of low symmetry crystal structures, that appear to occur due to enhanced electronic correlations a…
