Neutron scattering from local magnetoelectric multipoles: a combined theoretical, computational, and experimental perspective

Andrea Urru, Jian-Rui Soh, Navid Qureshi +4

We address magnetic neutron scattering in the presence of local non-centrosymmetric asymmetries of the magnetization density. Such inversion-symmetry breaking, combined with the ab…

Dynamic Jahn-Teller effect in the strong spin-orbit coupling regime

Ivica Zivkovic, Jian-Rui Soh, Oleg Malanyuk +15

Exotic quantum phases, arising from a complex interplay of charge, spin, lattice and orbital degrees of freedom, are of immense interest to a wide research community. A well-known…

Evidence of rotational and tilting disorder of ReO6 octahedra in single crystals of a 5d1 double perovskite Ba2CaReO6

Alasdair Nicholls, Jian-Rui Soh, Yikai Yang +4

We present results of an experimental study on single crystals of a 5d1 double perovskite Ba2CaReO6. Magnetization measurements reveal a weak splitting between zero-field-cooled an…

Polarisation and Temperature Dependence of Er:CaWO -- Towards a Solid-State Rare-Earth Ion-Doped Quantum Memory

Mikhael T. Sayat, Trevor R. Lee, Suchit Negi +6

In the endeavour of developing quantum memories, Er:CaWO has emerged as a promising rare-earth ion-doped (REID) crystal platform due to its long optical coherence times…

Magnetic structure of EuCdSb single-crystal thin-film

Eliot Heinrich, Ayano Nakamura, Shinichi Nishihaya +5

We investigate the magnetic order in single crystalline EuCdSb thin films using a combined theoretical and experimental approach. Resonant elastic x-ray scattering experime…

Coupling between CaWO phonons and Er dopants

Mikhael T. Sayat, Federico Pisani, Hin Lok Chang +8

We investigate the lattice dynamics of CaWO, a promising host crystal for erbium-based quantum memories, using inelastic neutron scattering together with density-functional per…
