Abstract
- It is rigorously demonstrated that spatially uniform magnetization oscillations in sufficiently small ellipsoidal nanoparticles can be unconditionally stable with respect to spatially nonuniform perturbations. The proof reveals the dominant stabilizing effect of exchange field which is mathematically manifested through the Poincare inequality.
