Ferromagnetic fragmented state in the pyrochlore Ho $_{2}$ Ru $_{2}$ O $_{7}$

F. Museur, J. Robert, F. Morineau +10

The consecutive magnetic ordering of the Ho and Ru ions in the pyrochlore Ho2Ru2O7 and their interplay are investigated by neutron scattering, magnetic and specific heat measuremen…

Satisfaction and Violation of the Fluctuation-Dissipation Relation in spin ice materials

F. Morineau, V. Cathelin, P. C. W. Holdsworth +5

We test the fluctuation-dissipation relation (FDR) in spin ice materials Dy $_{2}$ Ti $_{2}$ O $_{7}$ and Ho $_{2}$ Ti $_{2}$ O $_{7}$ by measuring both the magnetic noise and the out-of-phase part of t…

Dipolar-octupolar correlations and hierarchy of exchange interactions in Ce $_{2}$ Hf $_{2}$ O $_{7}$

Victor PorÃ©e, Anish Bhardwaj, Elsa Lhotel +9

High-resolution neutron spectroscopy on Ce $_{2}$ Hf $_{2}$ O $_{7}$ reveals a correlated state characterized by distinct dipolar scattering signals -- quasi-elastic and inelastic contributio…

Thermodynamics of the dipole-octupole pyrochlore magnet Ce $_{2}$ Hf $_{2}$ O $_{7}$ in applied magnetic fields

Anish Bhardwaj, Victor PorÃ©e, Han Yan +7

The recently discovered dipole-octupole pyrochlore magnet Ce $_{2}$ Hf $_{2}$ O $_{7}$ is a promising three-dimensional quantum spin liquid candidate which shows no signs of ordering at low t…

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…

Bond-dependent interactions and ill-ordered state in the honeycomb cobaltate BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$

A. Devillez, J. Robert, E. Lhotel +13

The ground state and Hamiltonian of the honeycomb lattice material BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$ hosting magnetic Co $^{2 +}$ , have been debated for decades. The recent proposal for an…
