About the 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…

Geometrically Frustrated Quadrupoles on the Pyrochlore Lattice and Generalized Spin Liquids

Kristian Tyn Kai Chung, Sylvain Petit, Julien Robert +1

As an instance of geometrical frustration with non-magnetic degrees of freedom, we explore the physics of local spin $S \geq 1$ moments on the pyrochlore lattice that interact via p…

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…
