Abstract
We present an exact expression of spin operators in terms of magnons and quasielectrons in ferromagnetism. Its relation to the Holstein-Primakoff expression is discussed. The result shows that the spin rotation of electrons is induced by a transformation of magnons and quasielectrons which is different from rotation.Keywords
