Spin-wave dynamics in the KCeS2 delafossite: A theoretical description of powder inelastic neutron-scattering data
S. M. Avdoshenko, A. A. Kulbakov, E. Häußler +4
Layered rare-earth delafossites with = Yb(III) or Ce(III) have received a lot of interest as potential hosts for a quantum spin-liquid ground state. Some systems of thi…
Stripe-yz magnetic order in the triangular-lattice antiferromagnet KCeS2
Anton A. Kulbakov, Stanislav M. Avdoshenko, Ines Puente-Orench +5
Yb- and Ce-based delafossites were recently identified as effective spin-1/2 antiferromagnets on the triangular lattice. Several Yb-based systems, such as NaYbO2, NaYbS2, and NaYbS…
Destruction of long-range magnetic order in an external magnetic field and the associated spin dynamics in Cu2GaBO5 and Cu2AlBO5 ludwigites
A. A. Kulbakov, R. Sarkar, O. Janson +12
The quantum spin systems CuM'BO (M' = Al, Ga) with the ludwigite crystal structure consist of a structurally ordered Cu sublattice in the form of three-leg ladders,…
Long-range magnetic order in the triangular lattice antiferromagnet KCeS
G. Bastien, B. Rubrecht, E. Haeussler +19
Recently, several putative quantum spin liquid (QSL) states were discovered in rare-earth based triangular-lattice antiferromagnets (TLAF) with the delafossite s…
Magnetic Properties of an Effective Spin- Triangular-Lattice Compound LiYbS
K. M. Ranjith, Ph. Schlender, Th. Doert +1
Here, we report the synthesis and magnetic properties of a Yb-based triangular-lattice compound LiYbS. At low temperatures, it features an effective spin- state du…
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$_…
