Some Considerations on Electronic Energy of Itinerant-electron Metamagnetic Materialswith Volume-dependent Exchange Energy

摘要

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