 This study demonstrated the feasibility of fabricating stretchable magnetic films with high growth temperature using metamagnetic FarH films. The resulting films exhibit a periodically wrinkled structure due to the large modulus mismatch between the FarH film and the press-drained PDMS substrate. This allows for effective control over the metamagnetic phase transition temperature, which increases by approximately 4K per 10% increase in press-drain. Furthermore, the films retain their stability even under tensile strains below the press-drain, making them suitable for applications in flexible magneto-electronic devices.
