  • The competing magnetic interaction in the spin-ice oxide compounds lead to emergent magnetic monopole excitations. Here, the authors study the critical dynamics near the monopole liquid-gas transition, and confirm predictions that these monopoles are also accompanied by an electric dipole.

  • The phase diagram of the unconventional superconductor Sr2RuO4 in both normal and superconducting states is mapped out using high-precision measurements of the elastocaloric effect, showing similarities to other unconventional superconductors as well as unique features.

  • Topological magnon bands in magnetic skyrmion lattices offer robust, unidirectional edge transport, crucial for advancing magnonic circuits and quantum transport studies. Here, Brillouin light scattering microscopy is used to detect intermediate wavelength magnons in Cu2OSeO3, revealing multipole excitation modes with inactive dipole character, including a novel quadrupole mode and, possibly, a sextupole mode, enhancing GHz frequency magnonic device design.

  • The dynamic properties of Néel skyrmions in magnetic thin films have remained elusive. Here, the authors report distinct resonances in Ir/Fe/Co/Pt heterostructures whose frequencies vary with the skyrmion configuration and multilayer architecture, thus opening a path to microwave applications.

  • Charge carriers in an engineered bilayer Mott insulator are predicted to form tightly bound, mobile pairs, glued together by string excitations of the antiferromagnetic order — a scenario that can be tested with quantum gas microscopy experiments.

  • The observation of three new classes of domain wall demonstrates the importance of topological disclination and dislocation defects in the helimagnet iron germanium, via analogy with grain boundaries in cholesteric liquid crystals.

  • LiHoF4, a dipolar Ising ferromagnet, is investigated near its transverse-field quantum critical point, showing that well-defined mesoscale quantum phase transitions arise when tilting the magnetic field away from the hard axis.
