Abstract
Ferromagnetism is obtained in solids when the magnetic moments of many electrons align. Antiferromagnetism and spin density waves describe oscillatory ordering of magnetic moments. The classical dipolar interaction between the electron moments (which is of order 10-5eV) is far too weak to explain the observed magnetic transition temperatures (which are of order 102–103 °K in transition metal and rare earth compounds).
