Query: Edge-modulated perpendicular magnetic anisotropy in [Co/Pd]n and
  L10-FePt thin film wires   Thickness modulation at the edges of nanostructured magnetic thin films is
shown to have important effects on their perpendicular magnetic anisotropy.
Thin film wires with tapered edges were made from [Co/Pd]20 multilayers or
L10-FePt films using liftoff with a double layer resist. The effect of edge
taper on the reversal process was studied using magnetic force microscopy and
micromagnetic modeling. In [Co/Pd]20 the anisotropy was lower in the tapered
edge regions which switched at a lower reverse field compared to the center of
the wire. The L10-FePt wires showed opposite behavior with the tapered regions
exhibiting higher anisotropy.
