The Fermi surface of PtCoO2 from quantum oscillations and electronic structure calculations
F. Arnold, M. Naumann, H. Rosner +9
The delafossite series of layered oxides include some of the highest conductivity metals ever discovered. Of these, PtCoO2, with a room temperature resistivity of 1.8 microOhmcm fo…
Effective Spin-1/2 Moments on a Yb Triangular Lattice: an ESR Study
Jörg Sichelschmidt, Burkhard Schmidt, Philipp Schlender +3
We investigated the spin dynamics by electron spin resonance (ESR) of the Yb-based, effective spin-1/2 delafossites NaYbO, AgYbO, LiYbS, NaYbS, and NaYbSe$_…
Magnetic frustration and spontaneous rotational symmetry breaking in PdCrO2
Dan Sun, Dmitry Sokolov, Jack Bartlett +8
In the triangular layered magnet PdCrO2 the intralayer magnetic interactions are strong, however the lattice structure frustrates interlayer interactions. In spite of this, long-ra…
Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO
Maja D. Bachmann, Aaron L. Sharpe, Arthur W. Barnard +6
Geometric electron optics may be implemented in solid state when transport is ballistic on the length scale of a device. Currently, this is realized mainly in 2D materials characte…
Oscillations in Interlayer Transport of Delafossites
Carsten Putzke, Maja D. Bachmann, Philippa McGuinness +10
Transport of electrons in a bulk metal is usually well captured by their particle-like aspects, while their wave-like nature is commonly harder to observe. Microstructures can be a…
Field-induced instability of the quantum-spin-liquid ground state in the triangular-lattice compound NaYbO
K. M. Ranjith, D. Dmytriieva, S. Khim +8
Polycrystalline samples of NaYbO are investigated by bulk magnetization and specific-heat measurements, as well as by nuclear magnetic resonance (NMR) and electron spin resonan…
