We report on a quantum critical behavior in the quasi-1D spin-1/2 zigzag frustrated chain antiferromagnet CaCoV_{2}O_{7}, induced by an applied magnetic field. Below T_{N}=3.3 K our zero-field neutron diffraction studies revealed the up-up-down-down

Frustration-induced dimensional reduction is manifested in lower dimensionality of magnetic correlations compared to that of the magnetic structure. Here the authors demonstrate the role of the uniform Dzyaloshinskii-Moriya interaction in the recentl

Theoretical studies of quantum magnetism typically assume idealised lattices with freely tunable parameters, which are difficult to realise experimentally. Zvyagin et al. perform challenging measurements at high pressures to tune and to accurately mo

We report on low-temperature heat-transport properties of the spin-1/2 triangular-lattice antiferromagnet Cs_{2}CuCl_{4}. Broad maxima in the thermal conductivity along the three principal axes, observed at about 5 K, are interpreted in terms of the

Metamagnets, which exhibit a transition from a low-magnetization to a high-magnetization state induced by the applied magnetic field, have recently been highlighted as promising materials for controllable broadband absorption. Here we show results of

The observation of spinon excitations in the $$S=\frac{1}{2}$$ S = 1 2 triangular antiferromagnet Ca3ReO5Cl2 reveals a quasi-one-dimensional (1D) nature of magnetic correlations, in spite of the nominally 2D magnetic structure. This phenomenon is kno
