Abstract:	Ferrite doped CoFe films with stripe domains are demonstrated to possess zero-field ferromagnetic resonance frequency above 5 GHz. The high resonance frequency is driven by the rotatable magnetic anisotropy propagated from the stripe domain structure and exchange coupling between rotatable ferrimagnetic spins and the ferromagnetic grains. The high temperature results show that these films have excellent thermal stability, which may have a great implication for microwave applications. © 2013 AIP Publishing LLC.
