Abstract
It is proposed a theoretical approach for magnons at finite temperature in a single-domain nanoparticle. Due to the spin wave quantization, the magnons have a finite spectrum, depending on the type, size and shape of the nanoparticle. The thermal fluctuations of the environment - considered as a thermal reservoir - is considered to be the cause of the nanoparticle nonequilibrium behavior, especially of the magnetization.
