  • Materials with ordered magnetic spiral phases can exhibit ferroelectricity and magnetoelectric effects, but applications are restricted by low magnetic-order temperatures. Here, the authors stabilize the magnetic spiral phase of YBaCuFeO5at room temperature by controlling the iron–copper chemical disorder.

  • CeCoIn5 is a d-wave heavy-fermion superconductor. By tuning the coupling between magnetic and superconducting order, a phase with inhomogeneous p-wave superconductivity can be detected, which coexists with d-wave superconductivity and spin-density-wave order.

  • Magnonic devices, based on the physics of spin-waves, are a potential alternative to process and store information that consume less energy and van der Waals crystals are candidate materials for such applications. Here, the authors investigate the magnetic ground state and spin-wave spectrum of ErBr3 finding that the dipolar interactions play a dominant role and allow for continuous control of topological excitations.

  • The coexistence of ferromagnetism and ferroelectricity in a multiferroic material often arises from complex magnetoelectric couplings. Here, the authors observe switching of domains in Mn2GeO4using neutron diffraction and develop a phenomenological theory to explain their results.

  • PbFeO3 is part of a family of lead based perovskites with many intriguing properties; however, difficulties in synthesis have hampered investigation. Here, the authors present a detailed study of the structure of PbFeO3 observing unique charge ordering and spin orientation among the constituent ions.

  • 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.

  • In heavy fermion metals, exotic states such as superconductivity depend to a large extent on whether unpaired electrons can become delocalized from the magnetic sites. The authors demonstrate that the primary driving force behind delocalization is the local environment of the rare earth ions and the strength of the resulting charge fluctuations.

  • 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.
