Ring-Exchange Interaction Effects on Magnons in Dirac Magnet CoTiO
Yufei Li, Thuc T. Mai, M. Karaki +20
The magnetic interactions that determine magnetic order and magnon energies typically involve only two spins. While rare, multi-spin interactions can also appear in quantum magnets…
Magnetic ground state of the Kitaev NaCoTeO spin liquid candidate
Weiliang Yao, Yang Zhao, Yiming Qiu +4
As a candidate Kitaev material, NaCoTeO exhibits intriguing magnetism on a honeycomb lattice that is believed to be -symmetric. Here we report a neutron diffractio…
Antiferromagnetic metal phase in an electron-doped rare-earth nickelate
Qi Song, Spencer Doyle, Grace A. Pan +28
Long viewed as passive elements, antiferromagnetic materials have emerged as promising candidates for spintronic devices due to their insensitivity to external fields and potential…
Beyond Single Tetrahedron Physics of Breathing Pyrochlore Compound Ba3Yb2Zn5O11
Rabindranath Bag, Sachith E. Dissanayake, Han Yan +11
Recently a new class of quantum magnets, the so-called breathing pyrochlore spin systems, have attracted much attention due to their potential to host exotic emergent phenomena. He…
Chemical tuning of a honeycomb magnet through a critical point
Austin M. Ferrenti, Maxime A. Siegler, Shreenanda Ghosh +9
BaCo2(AsO4)2 (BCAO) has seen extensive study since its initial identification as a proximate Kitaev quantum spin liquid candidate. Thought to be described by the highly anisotropic…
Magnetic field effects in an octupolar quantum spin liquid candidate
Bin Gao, Tong Chen, Han Yan +15
Quantum spin liquid (QSL) is a disordered state of quantum-mechanically entangled spins commonly arising from frustrated magnetic dipolar interactions. However, QSL in some pyrochl…
