FIELD: special materials.
SUBSTANCE: invention relates to materials used in spin-electronics - spintronics that are able sources of spins - spin injectors at room and higher temperatures in heterostructures FP/P wherein FP means ferromagnetic semiconducting material or ferromagnetic composite; P means nonmagnetic semiconductor or spin receiver. Proposed spintronic composition material comprises metal oxide and ferromagnetic metal wherein it comprises europium monooxide as metal oxide and α-iron as ferromagnetic metal in the following ratio of components, weight%: europium monoxide EuO, 75-85, and iron α-Fe, 15-25. Invention provides the development of spintronic composition material possessing high values of ferromagnetic saturation moment and semiconducting conductivity and prepared in the volume form.
EFFECT: improved preparing method, valuable properties of material.
