摘要: Magnetic properties of ferromagnetic metals and their alloys are essentially defined by itinerant electrons described relatively narrow energy bands. Nevertheless, thermodynamic such magnetic systems can quite often be quantitatively understood within the simple Heisenberg model [4.1]. Recently substantial progress has been made in description transition metals. Due to correlation effects, as Anderson model, metal atoms attain local moments, type ordering will exchange interactions.
