FERRITE MATERIAL Russian patent published in 2005 - IPC

Abstract RU 2257629 C1

FIELD: microwave engineering.

SUBSTANCE: proposed ferrite material that can be used in nonreciprocal microwave devices, such as valves and high-power circulators is based on Li-ferrospinel and has following elements in its composition, mass percent: Li₂O, 2.79 - 3.45; TiO₂, 0.001 - 5.74; ZnO, 7.57 - 7.99; MnO₂, 6.07 - 8.12; Fe₂O₃, 79.49 - 88.90; Co₃O₄, 0.33 - 0.97; Nb₂O₅, 1.90 - 2.22.

EFFECT: reduced width of spin-wave resonance line and dielectric and magnetic loss tangent in extremely high-frequency band at high saturation value.
