Single crystal growth, structure and magnetic properties of Pr2Hf2O7 pyrochlore
Monica Ciomaga Hatnean, Romain Sibille, Martin R. Lees +4
Large single crystals of the pyrochlore Pr2Hf2O7 have been successfully grown by the floating zone technique using an optical furnace equipped with high power Xenon arc lamps. Stru…
Coulomb spin liquid in anion-disordered pyrochlore TbHfO
Romain Sibille, Elsa Lhotel, Monica Ciomaga Hatnean +16
The charge ordered structure of ions and vacancies characterizing rare-earth pyrochlore oxides serves as a model for the study of geometrically frustrated magnetism. The organizati…
Stress-induced magnetic domain selection reveals a conical ground state for the multiferroic phase of Mn2GeO4
J. S. White, T. Honda, R. Sibille +6
At ambient pressure (P) and below 5.5 K, olivine-type Mn2GeO4 hosts a multiferroic (MF) phase where a multicomponent, i.e., multi-k magnetic order generates spontaneous ferromagnet…
Fully gapped superconductivity in the topological superconductor beta-PdBi2
P. K. Biswas, D. G. Mazzone, R. Sibille +8
The recent discovery of the topologically protected surface states in the beta-phase of PdBi2 has reignited the research interest in this class of superconductors. Here, we show re…
Spiral spin-liquid and the emergence of a vortex-like state in MnScS
Shang Gao, Oksana Zaharko, Vladmir Tsurkan +10
Spirals and helices are common motifs of long-range order in magnetic solids, and they may also be organized into more complex emergent structures such as magnetic skyrmions and vo…
Candidate quantum spin ice in the pyrochlore PrHfO
Romain Sibille, Elsa Lhotel, Monica Ciomaga Hatnean +5
We report the low temperature magnetic properties of the pyrochlore PrHfO. Polycrystalline and single-crystal samples are investigated using time-of-flight neutron spec…
