Incoherent magnetization reversals in elongated particles

The magnetization reversal modes for the rather small? elongated ferromagne tic particles are discussed. Results of analytic micromagnetics for prolate spheroids are compared with the available experimental data on elongated N i columns. A special emphasis is put on the role of magnetocrystalline and surface anisotropies. (C) 1999 Elsevier Science B.V. All rights reserved.
