The van der Waals ferromagnet Fe₃GaTe₂ exhibits above-room-temperature ferromagnetism and the interlayer magnetic coupling significantly sensitive to interlayer strain. This presentation reports our research on achieving electrical control of its magnetic properties using the piezostrain of the ferroelectric PMN-PT.
