N2 - Effects of the anisotropy and intergranular interaction in longitudinal media have been studied experimentally using micromagnetic simulation of torque. Two samples with different noise characteristics were compared in terms of the mean anisotropy field H-k, H-k distribution and exchange coupling stiffness C*. Simulation results showed very good agreement with the results previously produced with other techniques, including TEM, FMR, Vector VSM, Delta-M and Delta-T. (C) 2004 Elsevier B. V.
