Planar thermal Hall effect from phonons in cuprates

Lu Chen, Léna Le Roux, Gaël Grissonnanche +11

A surprising "planar" thermal Hall effect, whereby the field is parallel to the current, has recently been observed in a few magnetic insulators, and this has been attributed to ex…

Competing spin-orbital singlet states in the 4 $d^{4}$ honeycomb ruthenate Ag $_{3}$ LiRu $_{2}$ O $_{6}$

T. Takayama, M. Blankenhorn, J. Bertinshaw +25

When spin-orbit-entangled $d$ -electrons reside on a honeycomb lattice, rich quantum states are anticipated to emerge, as exemplified by the $d^{5}$ Kitaev materials. Distinct yet equ…

Nonmagnetic $J = 0$ State and Spin-Orbit Excitations in K $_{2}$ RuCl $_{6}$

H. Takahashi, H. Suzuki, J. Bertinshaw +10

Spin-orbit Mott insulators composed of $t_{2 g}^{4}$ transition metal ions may host excitonic magnetism due to the condensation of spin-orbital $J = 1$ triplons. Prior experiments sugge…

Pressure-induced collapse of spin-orbital Mott state in the hyperhoneycomb iridate $β$ -Li $_{2}$ IrO $_{3}$

T. Takayama, A. Krajewska, A. S. Gibbs +8

Hyperhoneycomb iridate $β$ -Li $_{2}$ IrO $_{3}$ is a three-dimensional analogue of two-dimensional honeycomb iridates, such as $α$ -Li $_{2}$ IrO $_{3}$ , which recently appeared as another playgr…

Probing the $J_{e f f} = 0$ ground state and the Van Vleck paramagnetism of the Ir $^{5 +}$ ions in the layered Sr $_{2}$ Co $_{0.5}$ Ir $_{0.5}$ O $_{4}$

S. Agrestini, C. -Y. Kuo, K. Chen +11

We report a combined experimental and theoretical x-ray magnetic circular dichroism (XMCD) spectroscopy study at the Ir- $L_{2, 3}$ edges on the Ir $^{5 +}$ ions of the layered hybrid…

Phase diagram and optical conductivity of La1.8-xEu0.2SrxCuO4

M. Autore, P. Di Pietro, P. Calvani +5

La1.8-xEu0.2SrxCuO4 (LESCO) is the member of the 214 family which exhibits the largest intervals among the structural, charge ordering (CO), magnetic, and superconducting transitio…
