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…
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 moments on the pyrochlore lattice that interact via p…
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…
Exploring possible magnetic monopoles-induced magneto-electricity in spin ices
Y. Alexanian, J. Saugnier, C. Decorse +7
The possibilities of combining several degrees of freedom inside a unique material have recently been highlighted in their dynamics and proposed as information carriers in quantum…
