Some considerations on electronic energy of itinerant-electron metamagnetic materials with volume-dependent exchange energy

摘要

Electronic energy of itinerant-electron metamagnetic materials is examined by taking into consideration volume-dependent exchange energy between up and down spin elec- trons. 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 vale of the exchange energy may be evaluated.
