Topological band structure of excitons in octochlore KTb $_{3}$ F $_{10}$ : an analog of the Luttinger Semimetal

Olivier Demortier, Françoise Damay, Paul McClarty +3

Understanding the symmetry and topology of band structures in crystalline solids has been among the defining themes of a generation of condensed matter physicists, with implication…

Exotic magnetism and persistent short-range spin correlations in a frustrated honeycomb lattice antiferromagnet

M. Barik, Q. Faure, F. Damay +3

Two-dimensional high-spin bipartite honeycomb networks, where anisotropy, competing exchange interactions, and spin fluctuations interplay, provide an alternative platform to test…

Origin of the magnetic ground state of Tb $_{2}$ Ir $_{2}$ O $_{7}$

Y. Alexanian, E. Lhotel, J. Robert +10

Magnetic-rare-earth pyrochlore iridates exhibit a rich variety of unconventional phases, driven by the complex interactions within and between the rare-earth and the iridium sublat…

From hierarchical triangular spin liquid to multi- $q$ spin texture in spinel GeFe $_{2}$ O $_{4}$

L. Chaix, J. Robert, E. Chan +16

Combining macroscopic measurements, neutron scattering and modeling, we identify in the GeFe $_{2}$ O $_{4}$ spinel a correlated paramagnetic state resulting from the predominance of thir…

Impact of disorder in Nd-based pyrochlore magnets

Mélanie Léger, Florianne Vayer, Monica Ciomaga Hatnean +11

We study the stability of the antiferromagnetic all-in--all-out state observed in dipolar-octupolar pyrochlores that have neodymium as the magnetic species. Different types of diso…

From one- to two-magnon excitations in the S=3/2 magnet $β$ -CaCr $_{2}$ O $_{4}$

M. Songvilay, S. Petit, F. Damay +7

We apply neutron spectroscopy to measure the magnetic dynamics in the S=3/2 magnet $β$ -CaCr $_{2}$ O $_{4}$ (T $_{N}$ =21 K). The low-energy fluctuations, in the ordered state, resemble large…

Fragmented monopole crystal, dimer entropy and Coulomb interactions in Dy $_{2}$ Ir $_{2}$ O $_{7}$

V. Cathelin, E. Lefrançois, J. Robert +12

Neutron scattering, specific heat and magnetisation measurements on both powders and single crystals reveal that Dy $_{2}$ Ir $_{2}$ O $_{7}$ realizes the fragmented monopole crystal state in…

Long range order in the dipolar XY antiferromagnet Er $_{2}$ Sn $_{2}$ O $_{7}$

S. Petit, E. Lhotel, F. Damay +3

Er $_{2}$ Sn $_{2}$ O $_{7}$ remains a puzzling case among the extensively studied frustrated compounds of the rare-earth pyrochlore family. Indeed, while a first order transition towards a l…

Magnetic charge injection in spin ice: a new way to fragmentation

E. Lefrançois, V. Cathelin, E. Lhotel +10

The complexity embedded in condensed matter fertilizes the discovery of new states of matter, enriched by ingredients like frustration. Illustrating examples in magnetic systems ar…

Field induced phase diagram of the XY pyrochlore antiferromagnet Er $_{2}$ Ti $_{2}$ O $_{7}$

E. Lhotel, J. Robert, E. Ressouche +9

We explore the field-temperature phase diagram of the XY pyrochlore antiferromagnet Er $_{2}$ Ti $_{2}$ O $_{7}$ , by means of magnetization and neutron diffraction experiments. Depending on t…
