Vortex order in magnetic frustrated GeNiO and GeCoO spinels
K. Beauvois, J. Robert, M. Songvilay +11
In the search for new spin textures based on singular magnetic objects like Bloch-points or vortices, spinel compounds emerge as an interesting playground due to the interplay betw…
About the origin of the magnetic ground state of TbIrO
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- spin texture in spinel GeFeO
L. Chaix, J. Robert, E. Chan +16
Combining macroscopic measurements, neutron scattering and modeling, we identify in the GeFeO spinel a correlated paramagnetic state resulting from the predominance of thir…
Bond-dependent interactions and ill-ordered state in the honeycomb cobaltate BaCo(AsO)
A. Devillez, J. Robert, E. Lhotel +13
The ground state and Hamiltonian of the honeycomb lattice material BaCo(AsO) hosting magnetic Co, have been debated for decades. The recent proposal for an…
