Quantum spin systems exhibit an enormous range of collective excitations, but their spin waves, gapped triplons, fractional spinons, or yet other modes are generally held to be mutually exclusive. Here we show by neutron spectroscopy on SeCuO$_3$ tha

High field magnetization measurements in pulsed fields up to 65 T have been performed on ${\mathrm{FePS}}_{3}$, which is nominally a good example of a two-dimensional Ising-like antiferromagnet on a honeycomb lattice. Measurements with the field para

We measured NMR and magnetic susceptibility for the quasi-two-dimensional, weakly $XY$-like, spin-$1/2$ square-lattice Heisenberg antiferromagnet $[\mathrm{CuCl}{(\mathrm{pyz})}_{2}]{\mathrm{BF}}_{4}$ (pyz = pyrazine $=\phantom{\rule{0.16em}{0ex}}{\m

In the Ca1−xLaxFeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure, high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition at

The strongly correlated insulator Ca2RuO4 is considered as a paradigmatic realization of both spin-orbital physics and a band-Mott insulating phase, characterized by orbitally selective coexistence of a band and a Mott gap. We present a high resoluti

Resonant inelastic X-ray scattering (RIXS) experiments performed at the oxygen-$K$ edge on the iridate perovskites {\SIOS} and {\SION} reveal a sequence of well-defined dispersive modes over the energy range up to $\sim 0.8$ eV. The momentum dependen

The antiferromagnetic compound $\mathrm{Ba}(\mathrm{TiO}){\mathrm{Cu}}_{4}{({\mathrm{PO}}_{4})}_{4}$ contains square cupola of corner-sharing ${\mathrm{CuO}}_{4}$ plaquettes, which were proposed to form effective quadrupolar order. To identify the ma

We use resonant inelastic x-ray scattering (RIXS) at the Cu L3 edge to measure the charge and spin excitations in the “half-stuffed” Cu-O planes of the cuprate antiferromagnet Ba2Cu3O4Cl2. The RIXS line shape reveals distinct contributions to the

We report magnetic and thermodynamic properties of a 4d1 (Mo5+) magnetic insulator MoOPO4 single crystal, which realizes a J1−J2 Heisenberg spin-1/2 model on a stacked square lattice. The specific-heat measurements show a magnetic transition at 16
