  • The interaction between spins in magnetic materials gives rise to a number of interesting effects. An example is the discovery of an unusual magnetic state based on a long-range ordering force between magnetic domain walls that is analogous to the interaction between protons and neutrons in atomic nuclei.

  • The presence of guest atoms—known as rattlers—in the cages of some clathrate structures is considered to be responsible for the low thermal conductivity of the materials. Neutron spectroscopy provides important evidence regarding the actual phonon dispersion in the material, and the precise way in which this is influenced by rattlers.

  • An electron subject to a periodic potential and a constant electric field exhibit oscillatory dynamics, known as Bloch oscillations. Here, the authors demonstrate a magnetic analogue of Bloch oscillations in a ferromagnetic near-Ising chain, where magnetic excitations oscillate in response to a magnetic field.

  • Suppression of quantum tunneling in molecular magnets is key for their magnetic behaviours to be exploitable. Here, the authors show that tuning the geometry of lanthanide single-ion magnets leads to a suppression of the quantum tunneling, finding a three-fold reduction of the tunnel splitting upon changing the crystal field symmetry.

  • LaPt2Si2 exhibits an intriguing interplay of superconductivity and charge density wave order, but the nature of its density wave transitions is controversial. Here, high-resolution X-ray diffraction reveals the temperature dependence of a series of density wave and structural transitions in this material.
