  • Combining topological phenomena with correlated electron physics could help enable next-generation quantum devices. Here, the authors demonstrate a topological metal-insulator transition within the ferromagnetic phase of K2Cr8O16.

  • Experimental studies of frustrated spin systems such as pyrochlore magnetic oxides test our understanding of quantum many-body physics. Here the authors show experimentally that Tb2Hf2O7 may be a model material for investigating how structural disorder can stabilize a quantum spin liquid phase.

  • Van Hove singularities have the potential to drive unconventional magnetic states in Kagomes. Here, the authors provide experimental and theoretical results suggesting a van Hove singularity-assisted spin density wave in the Kagome metal CeTi3Bi4.

  • Skyrmion crystals, where skyrmions are arranged close packed in a triangular lattice arise due to the superposition of three magnetic spin spirals, each with a distinct wave vector, Q. Such skrymion crystals have been found in a diverse array of materials. Here, Park et al find a short wavelength (or dense skyrmion) limit of this skyrmion crystal structure in Co1/3TaS2, a metallic triangular lattice antiferromagnet, in the form of a triple Q magnetic ordering, with four magnetic sublattices.’

  • A detailed neutron-scattering study reveals a quantum spin liquid behaviour in Ce2Sn2O7 originating from its higher-order magnetic multipolar moments acting on the geometrically frustrated pyrochlore lattice.

  • A detailed and systematic neutron scattering study of rare-earth pyrochlore magnet Pr2Hf2O7 provides evidence for a quantum spin ice state, and emergent lattice quantum electrodynamics consistent with theoretical predictions.
