Examining the Magnetic Skyrmion Phase in GaV₄S₈
A PHAROS laser equipped with an I-OPA was used to investigate the magnetic skyrmion phase in GaV₄S₈. It was found that skyrmions show a coherent spin precession that can be detected using an ultrafast magneto-optical Kerr effect (MOKE) experiment. The optical detection of the skyrmion phase is crucial for its use in future spintronics devices.
The paper detailing this research, entitled: “Slowdown of photoexcited spin dynamics in the non-collinear spin-ordered phases in skyrmion host GaV4S8,” appears in Nature Communications. One of the co-authors, Dr. Kestutis Budzinauskas, is a member of the Light Conversion team.
