Abstract
Magnetometric and relaxometric data from SPM particles are revisited, leadi ng to a double conclusion rather different from the original one: accountin g for the anisotropy energy not only allows a considerable improvement of t he fit of the data to theory, but it also invalidates the conclusion obtain ed from the high field data (without accounting for anisotropy) concerning an important reduction of the diffusion coefficient by the coating of the p articles.
