VANADIUM-CONTAINING SPIN-GLASS MAGNETIC MATERIAL Russian patent published in 2023 - IPC C04B35/495 C04B35/26 H01F1/01 

FIELD: ceramic materials.

SUBSTANCE: invention relates to development of new ceramic oxide materials with a magnetic state of spin glass and can find application in the chemical industry, electronic engineering, spintronics, in particular, for the development of models of new types of magnetic memory devices. The spin-glass magnetic material NaZnFe₂(VO₄)₃ includes iron, oxygen, vanadium, sodium and zinc, with the following component ratio, at.%: iron - 10.53, vanadium - 15.79, sodium - 5.26 and zinc - 5.26, oxygen - 63.16. The compound is synthesized by a reaction in the solid phase from Na₂CO₃, Fe₂O₃, ZnO, V₂O₅ during 2 annealings lasting 24 hours at temperatures of 630°C, 640°C and normal pressure.

EFFECT: production of a new oxide ceramic material with a spin glass magnetic state.
