Metastability of the Skyrmion Lattice in GdRu_{2}Si_{2} Revealed by Ultrasound
{{output}}
We report on the low-temperature magnetoelastic properties of the skyrmion-lattice compound GdRu_{2}Si_{2} under magnetic fields applied along the [001] axis. Our sound-velocity measurements reveal a series of pronounced anomalies related to the skyrmion-latti... ...
