Observation of asymmetrical pinning of domain walls in notched Permalloy nanowires using electron holography
Field-driven domain-wall motion and pinning in notched Permalloy nanowires have been observed using electron holography and Lorentz microscopy. Transverse domain walls (TDWs) were identified and diffe...

We present the determination of the wavelength and phase of propagating spin waves in magnetic microstructures made of Ni81Fe19 using the shorted end of a coplanar waveguide for local excitation. The spin wave characteristics have been measured by phase resolved Brillouin light scattering microscopy. This recently developed technique allows for the unambiguous experimental visualization of the phase structure of propagating spin waves and is employed here to magnetic microstructures. The results show an excellent agreement with the theoretically predicted spin-wave dispersion relations. ©2009 American Institute of Physics

  15. The material parameters used for the calculation of the spin-wave dispersion are: Saturation magnetization Ms=860  G Gyromagnetic ratio: gamma=0.0176  GHz/Oe Exchange stiffness constant: A=1.6×10−6  erg/cm.
  16. The effective quantization length was defined by measuring the transverse intensity profile and was found to be 1  µm for the maximum applied magnetic field (570 Oe) and decreased by approximately 200 nm when reducing the magnetic field to 180 Oe. This effect is well understood and is described in detail in Ref. 17. However, these changes in the quantization length cause only minor variations in the dispersion relation and are therefore neglected in the following calculations.
