Abstract
Magnetic nanoparticles are an object of current interest and in particular an interesting size dependence of the frequency of the main resonance peak has recently been observed in CoNi nanoparticles [1]. In this paper we provide a theoretical treatment of spin-wave excitations in ferromagnetic particles; the above mentioned resonance mode is identified as being a surface mode.
