Query: Tailoring the magnetic properties of Fe asymmetric nanodots   Asymmetric dots as a function of their geometry have been investigated using
three-dimensional (3D) object oriented micromagnetic framework (OOMMF) code.
The effect of shape asymmetry of the disk on coercivity and remanence is
studied. Angular dependence of the remanence and coercivity is also addressed.
Asymmetric dots are found to reverse their magnetization by nucleation and
propagation of a vortex, when the field is applied parallel to the direction of
asymmetry. However, complex reversal modes appear when the angle at which the
external field is applied is varied, leading to a non monotonic behavior of the
coercivity and remanence.
