"Unlocking the Power of Rare Earth Magnets: Generating Biskyrmions"

Researchers have generated high-density, spontaneous magnetic biskyrmions in a rare earth magnet without the need for an external magnetic field. By studying the negative thermal expansion of a lattice in a holmium-cobalt compound, the team observed the formation of stable biskyrmions across a wide temperature range. This discovery could have significant implications for the development of spintronic storage devices and other applications in the field of magnetism.
