Abstract
A new method is presented to compute the demagnetization tensor of particles of arbitrary shape. By means of a Fourier space approach it is possible to compute analytically the Fourier representation of the demagnetization tensor for a broad class of magnetic nanoparticles. Then, specifying the direction of the uniform magnetization, the demagnetizing field and the magnetostatic energy associated with the particle can be evaluated. (C) 2004 Elsevier B.V.
