Flexible Heteroepitaxy of CoFe 2 O 4 /Muscovite Bimorph with Large Magnetostriction
Abstract
Van der Waals epitaxy was used to fabricate a bimorph composed of ferrimagnetic cobalt ferrite (CoFe 2O 4, CFO) and flexible muscovite. The combination of X-ray diffraction and transmission electron microscopy was conducted to reveal the heteroepitaxy of the CFO/muscovite system. The robust magnetic behaviors against mechanical bending were characterized by hysteresis measurements and magnetic force microscopy, which maintain a saturation magnetization (Ms) of ~120–150 emu/cm 3 under different bending states. The large magnetostrictive response of the CFO film was then determined by digital holographic microscopy, where the difference of magnetostrction coefficient (Δλ) is -104 ppm. We attribute the superior performance of this bimorph to the nature of weak interaction between film and substrate. Such a flexible CFO/muscovite bimorph provides a new platform to develop next-generation flexible magnetic devices.
