Role of alkaline metal in the rare-earth triangular antiferromagnet KYbO
Franziska GruÃler, Mamoun Hemmida, Sebastian Bachus +4
We report crystal structure and magnetic behavior of the triangular antiferromagnet KYbO, the A-site substituted version of the quantum spin liquid candidate NaYbO. The rep…
Magnetic frustration in a metallic fcc lattice
Oliver Stockert, Jens-Uwe Hoffmann, Martin Mühlbauer +9
Magnetic frustration in metals is scarce and hard to pinpoint, but exciting due to the possibility of the emergence of fascinating novel phases. The cubic intermetallic compound Ho…
Field evolution of the spin-liquid candidate YbMgGaO
Sebastian Bachus, Ilia A. Iakovlev, Yuesheng Li +7
We report magnetization, heat capacity, thermal expansion, and magnetostriction measurements down to millikelvin temperatures on the triangular antiferromagnet YbMgGaO. Our dat…
Gapped ground state in the zigzag pseudospin-1/2 quantum antiferromagnetic chain compound PrTiNbO6
Yuesheng Li, Sebastian Bachus, Yoshifumi Tokiwa +2
We report a single-crystal study on the magnetism of the rare-earth compound PrTiNbO that experimentally realizes the zigzag pseudospin- quantum antiferromagnetic…
Gapless spin-liquid state in the structurally disorder-free triangular antiferromagnet NaYbO
Lei Ding, Pascal Manuel, Sebastian Bachus +8
We present the structural characterization and low-temperature magnetism of the triangular-lattice delafossite NaYbO. Synchrotron x-ray diffraction and neutron scattering exclu…
Absence of zero-point entropy in a triangular Ising antiferromagnet
Yuesheng Li, Sebastian Bachus, Yoshifumi Tokiwa +2
Frustrated Ising magnets host exotic excitations, such as magnetic monopoles in spin ice. The ground state (GS) in this case is characterized by an extensive degeneracy and associa…
Partial up-up-down order with the continuously distributed order parameter in the triangular antiferromagnet TmMgGaO4
Yuesheng Li, Sebastian Bachus, Hao Deng +6
Frustrated quasidoublets without time-reversal symmetry can host highly unconventional magnetic structures with continuously distributed order parameters even in a single-phase cry…
Rearrangement of uncorrelated valence bonds evidenced by low-energy spin excitations in YbMgGaO4
Yuesheng Li, Sebastian Bachus, Benqiong Liu +6
DC-magnetization data measured down to 40 mK speak against conventional freezing and reinstate YbMgGaO as a triangular spin-liquid candidate. Magnetic susceptibility measured p…
Quantum-critical phase out of frustrated magnetism in a strongly correlated metal
Hengcan Zhao, Jiahao Zhang, Meng Lyu +11
Strange-metal phenomena often develop at the border of antiferromagnetic order in strongly correlated metals. It has been well established that they can originate from the fluctuat…
