IRON-MANGANESE VANADATE WITH MAGNETIC STATE OF SPIN GLASS Russian patent published in 2024 - IPC C04B35/495 C04B35/26 H01F1/01

Abstract RU 2824621 C1

FIELD: various technological processes.

SUBSTANCE: invention relates to development of new materials with magnetic state of spin glass and can be used in chemical industry, electronic engineering, spintronics. Spin-glass magnetic material NaMnFe₂(VO₄)₃ contains iron, oxygen, vanadium, sodium and manganese at the following ratio of components, at.%: iron 10.53, vanadium 15.79, sodium 5.26, manganese 5.26, oxygen 63.16. Compound is synthesized by reaction in solid phase from oxides Na₂CO₃, Fe₂O₃, MnCO₃, V₂O₅ during 2 annealing for 24 hours at temperature of 600 °C and 650 °C in air.

EFFECT: obtaining a novel oxide ceramic material with a magnetic state of spin glass.
