Abstract

Magnetic thin films are indispensable in flexible devices, which necessitate methods to fabricate flexible magnetic thin films. In this work, we present a method to fabricate wrinkled FeRh flexible films via a coating and transfer process. The obtained FeRh/PDMS films have random patterns of wrinkles with a mean periodicity of 10 μm. From the curvature dependent magnetic measurements, it can be determined that the magnetic properties of the obtained wrinkled FeRh flexible films are insensitive to flexing up to a radius of curvature of 1.5 mm, making it promising for applications in flexible devices.
