Spin-half Heisenberg antiferromagnet on a symmetric sawtooth chain: Rotation-invariant Green's functions and high-temperature series

Taras Hutak, Taras Krokhmalskii, Oleg Derzhko +1

We apply the rotation-invariant Green's function method to study the finite-temperature properties of a sawtooth-chain (also called -chain) antiferromagnetic Heisenber…

Non-Coplanar Magnetic Orders in Classical Square-Kagome Antiferromagnets

Martin Gembé, Heinz-Jürgen Schmidt, Ciarán Hickey +3

Motivated by the recent synthesis of a number of Mott insulating square-kagome materials, we explore the rich phenomenology of frustrated magnetism induced by this lattice geometry…

Magnetism of the - square-kagome lattice antiferromagnet

Johannes Richter, Jürgen Schnack

The spin- Heisenberg antiferromagnet on the square-kagome (SK) lattice has attracted growing attention as a model system of highly frustrated quantum magnetism. A further moti…

Metal-organic kagome systems as candidates to study spin liquids, spin ice or the quantum anomalous Hall effect

Adam Hassan Denawi, Xavier Bouju, Mathieu Abel +2

We present the results of first-principle calculations using the Vienna Ab-initio Simulation Package (VASP) for a new class of organometallics labeled TM3C6O6 (TM =Sc, Ti, V, Cr, F…

Melting of magnetization plateaus for kagome and square-kagome lattice antiferromagnets

H. Schlüter, J. Richter, J. Schnack

Unconventional features of the magnetization curve at zero temperature such as plateaus or jumps are a hallmark of frustrated spin systems. Very little is known about their behavio…

Ground state selection by magnon interactions in the fcc antiferromagnet

R. Schick, O. Götze, T. Ziman +3

We study the nearest-neighbor Heisenberg antiferromagnet on a face-centered cubic lattice with arbitrary spin S. The model exhibits degenerate classical ground states including two…
