The problem of quantum fluctuations in magnetic nanostructures is discussed by considering a linear chain of a finite number of atoms with the electron spins of neighboring atoms interacting via exchange as in Heisenberg's theory of ferromagnetism. Electromagnetic magnetic dipole radiation from a spin flip wave is calculated. It is shown that radiation energy flux calculations including electromagnetic field quantum fluctuations give much larger values than for the averaged field. The radiation decay due to spin interaction to the quantized electromagnetic field is estimated.
