Electronic energy of itinerant-electron metamagnetic materials is examined by taking into consideration volume-dependent exchange energy between up and down spin electrons. In particular, the average value of the electronic energy is formulated in terms of the energy bandwidth which is closely related to volume; from the above average value, the average value of the exchange energy may be evaluated.
