Abstract
The process of nucleation of magnetization reversal in bulk materials, by creating pairs of one-dimensional, planar Bloch or Ne\ifmmode\acute\else\textasciiacute\fi{}el walls, is extended here to the creation of spherical or cylindrical nuclei. Numerical integration of the appropriate differential equation leads to a saddle point in energy, which gives the barrier to be overcome for reversing the magnetization. The results for both cases are rather similar to the planar ones, but for vanishingly small fields the energy of the nucleus of a reversal structure tends to infinity, which means that it takes some finite field for any reversal to nucleate.
