METHOD OF OBTAINING THIN-FILM OXIDE MATERIAL ALLOYED WITH FERROMAGNETIC METAL IONS FOR SPINTRONICS Russian patent published in 2009 - IPC H01F41/20 C01F17/00 C30B29/16 

FIELD: production processes; electronics.

SUBSTANCE: invention refers to obtaining thin films of materials that can be used in devices of systems of semi-conducting spin electronics. Method of obtaining thin-film oxide material alloyed with ferromagnetic metal ions involves spraying of precursor on the carrier in low-density atmosphere at high temperatures. Spraying is carried out by evaporating initial granular powder alloyed with europium oxide iron (II) with particle size of 0.2-0.3 mm in vacuum (1÷5)·10^-5 torr when it is supplied to evaporator heated up to 2500-3000°C with velocity of 1-10 mg/s, at that, the carrier is located above evaporator at the distance of 8-12 cm.

EFFECT: obtaining thin film of semi-conducting spintron material with high degree of magnetisation and capable of being a spin ejector in devices of semi-conducting spin electronics at indoor temperature and temperature higher than the indoor one.
