Elucidating magnetic structure with optical dopants: erbium-doped GdSiO
Luke S. Trainor, Masaya Hiraishi, J. -R. Soh +1
The narrowness of the optical transitions of rare-earth-ion dopants makes them highly sensitive probes of their environment. We measured the optical transitions Er dopants t…
Magnetic and electronic structure of the layered rare-earth pnictide EuCdSb
J. -R. Soh, C. Donnerer, K. M. Hughes +4
Resonant elastic X-ray scattering (REXS) at the Eu edge reveals an antiferromagnetic structure in layered EuCdSb at temperatures below = 7.4 K with a m…
Coupling of magnetic order and charge transport in the candidate Dirac semimetal EuCdAs
M. C. Rahn, J. -R. Soh, S. Francoual +7
We use resonant elastic x-ray scattering to determine the evolution of magnetic order in EuCdAs below \,K, as a function of temperature and applied magnet…
An ideal Weyl semimetal induced by magnetic exchange
J. -R. Soh, F. de Juan, M. G. Vergniory +15
Weyl semimetals exhibit exceptional quantum electronic transport due to the presence of topologically-protected band crossings called Weyl nodes. The nodes come in pairs with oppos…
Spin waves and three-dimensionality in the high-pressure antiferromagnetic phase of SrCu(BO)
E. Fogh, G. Giriat, M. E. Zayed +11
Quantum magnetic materials can provide explicit realizations of paradigm models in quantum many-body physics. In this context, SrCu(BO) is a faithful realization of the…
Optical spectroscopy of single- and two-ion transitions in an antiferromagnetic stoichiometric rare-earth crystal
Masaya Hiraishi, Gabrielle A. Hunter-Smith, Gavin G. G. King +5
We characterise optical transitions of neodymium ions (Nd3+) in antiferromagnetic neodymium gallate (NdGaO3) with applied fields up to 3 T. The magnetic phase of this material has…
