Abstract
The exchange constants A and the g factors for CoxNi1-x microspheres are es timated by comparing theoretical calculations of size-dependent resonance m odes with the experimental data of spherical monodisperse Co-Ni particles. Only cylindrically symmetric modes are studied. The deviation from previous ly reported values is presented. (C) 2000 Elsevier Science B.V. All rights reserved.
