Query: Effect of Notch Structure on Magnetic Domain Movement in Planar
  Nanowires   We present the direct observation of magnetic domain motion in permalloy
nanowires with notches using a wide-field Kerr microscopy technique. The domain
wall motion can be modulated by the size and shape of the notch structure in
the nanowires. It is demonstrated that the coercive fields can be tuned by
modulating the notches. The experimental results are consistent with the
micro-magnetic simulation results. The relationship between the notch angle and
the domain nuclease are also studied. This work is useful for the design and
development of the notch-based spintronic devices.
