| Popis: | The theory of spin waves in metals according to the energy band theory of ferromagnetism is reviewed. The RPA calculation of spin wave energies is shown to be inconsistent with the t-matrix criterion for the occurrence of ferromagnetism at low densities. An improved method of calculating spin wave energies which leads to consistent results is described. |
