Abstract :
The Stoner-Wohlfarth model needs some modifications in order to take account of real anisotropy of monocrystal nanoparticles. Such a modified model predicts a qualitatively new behavior for the switching of the magnetization of such a particle. We provide the first experimental evidence of such a behavior
