Abstract: A comprehensive investigation of the magnetic properties and high frequency characteristics of NiFe/MnIr bilayers with regards to oblique deposition angle was conducted in conjunction with an analysis based on the Landau-Lifshitz- Gilbert equation. It was found that exchange bias can be significantly enhanced with the variation of oblique deposition angle, which is interpreted in terms of the formation of inclined columnar structure of the films often observed in samples fabricated by this oblique deposition technique. Moreover, the uniaxial magnetic anisotropy field and the resonance frequency are increased with the increasing of oblique deposition angle. The variations of effective Gilbert damping factor and the frequency linewidth with oblique deposition angle are also presented and discussed in details. © 2013 American Institute of Physics.
