Abstract Distinct skyrmion phases at room temperature hosted by one material offer additional degree of freedom for the design topology-based compact and energetically-efficient spintronic devices. The field has been extended to low-dimensional magnets with discovery magnetism in two-dimensional van der Waals magnets. However, creating multiple 2D magnets, especially above temperature, remains a major challenge. Here, we report experimental observation mixed-type skyrmions, exhibiting both...
