FERRITE MATERIAL Russian patent published in 2016 - IPC H01F1/34 

FIELD: electronic equipment.

SUBSTANCE: invention concerns ferrite materials with large values of spin wave line width for use in microwave range, including production of ferrites for devices of high power level of centimetre wavelength range. Technical result of invention is obtaining of ferrite material with high value of spin wave line width with magnetisation saturation of 1,800 Gs, ferromagnetic resonance width 40 Oe, real component of dielectric permittivity of 15.0, dielectric loss angle tangent of not more than 2-10^-4, Curie point of not less than 200 °C and spin wave line width at frequency of 9.5 GHz at least of 10 Oersted. Ferrite material contains, wt% yttrium oxide (Y₂O₃) - 45.0-45.5, samarium oxide (Sm₂O₃) - 1.2-1.3, iron oxide (Fe₂O₃) is rest.

EFFECT: proposed composition allows creating ferrite material with above parameters for production and development of microwave devices of high power level.
