Abstract :
The static wall coercive force of thin ferromagnetic films has been calculated from a model of conservative wall energy. The spatial dependence of the wall energy γw is assumed to be given by the mean value of the local anisotropy energy, averaged over a coupling volume of the wall. The result of the calculation shows that 
where the structure constant 
includes the local anisotropy, 
is the mean diameter of a region with constant anisotropy (for instance crystallites), 
is the wall width; and 
is the coupling length parallel to the wall.
