T. Schrefl et al., A HIGHER-ORDER FEM-BEM METHOD FOR THE CALCULATION OF DOMAIN PROCESSESIN MAGNETIC NANO-ELEMENTS, IEEE transactions on magnetics, 33(5), 1997, pp. 4182-4184
The Gilbert equation of motion is solved for magnetic nano-elements of
arbitrary shape using a hybrid finite element/boundary element method
, NiFe elements show small scale domains in the remanent state, if a u
niaxial anisotropy parallel to the short axis is assumed, In bars with
one pointed end, the formation of the domains starts from the fiat en
ds, Narrow elements with a width smaller than 0.2 mu m remain in a nea
rly single domain state.
