  • Hexagonal manganites are multiferroic materials that can exhibit magnetoelectric coupling and electrically conducting domain walls. Here, the authors produce yttrium manganite withp-type conductivity, useful for devices, by using excess oxygen to introduce point defects in the crystal lattice.

  • Artificial spin ice formed of nanomagnets arranged on a lattice mimics frustrated magnetism seen in condensed matter. By controlling magnetic interactions, theoretically predicted phase transitions are now observed in artificial kagome-lattice spin ice.

  • Artificial spin ices are metamaterials displaying fascinating phenomena arising from the collective behaviour of nanoscale magnets. We review recent developments in terms of emergent magnetic monopoles, phase transitions, dynamics and geometries, and discuss future directions for research and potential applications.
