Abstract: Abstract Low-temperature magnetothermodynamics of a highly frustrated spin-1/2 Heisenberg square bilayer with the antiferromagnetic intra-dimer interaction and ferromagnetic inter-dimer interaction is governed by localized many-magnon eigenstates, which can be described by the effective ferromagnetic spin-1/2… read more here.

Abstract: We study frustrated spin-1/2 dimer systems in two dimensions with a bilayer structure, where spins are ferromagnetically coupled in dimers. Our model includes frustrated two-spin exchange interactions as well as four-spin interaction. We pay particular… read more here.

DOI: 10.1103/physrevb.101.144407
Abstract: Magnetization plateaux emerging in quantum spin systems due to spontaneously breaking of translational symmetry have been reported both theoretically and experimentally. The broken symmetry can induce reconstruction of elementary excitations such as Goldstone and Higgs… read more here.

DOI: 10.1103/physrevb.95.184424
Abstract: We have performed magnetic susceptibility, heat capacity, muon spin relaxation, and neutron scattering measurements on three members of the family Ba3MRu2O9, where M = In, Y and Lu. These systems consist of mixed-valence Ru dimers… read more here.
