Omnidirectional zero-field ferromagnetic resonance driven by rotatable anisotropy in FeNi/FeMn bilayers without exchange bias

Abstract In this work, the zero- field GHz frequency permeability spectra and the rotatable anisotropy of FeMn/FeNi bilayers are investigated. Omnidirectional zero-field ferromagnetic resonance (FMR) driven by rotatable anisotropy can be achieved in the FeMn/FeNi bilayers without exchange bias. Inst...
