METHOD OF OBTAINING Mn-Fe-CONTAINING SPIN-GLASS MAGNETIC MATERIAL Russian patent published in 2018 - IPC C30B9/04 C30B9/12 C30B33/10 C30B29/22 C01B35/12 H01F1/01 H01L43/10 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of technological processes associated with obtaining a new magnetic material with a magnetic state such as a spin glass, and can find application in developing models of new types of modern electronics devices. Method of obtaining Mn-Fe-containing spin-glass material includes drying the compounds making up the mixture at a temperature of 105 °C for 6 hours, melting them in a furnace, preparing solutions-melts in platinum 100 cm³ crucible at T=1,100 °C successive fusion of mixtures of Bi₂Mo₃O₁₂ and B₂O₃ powders, then Mn₂O₃ and Fe₂O₃ are added to the melt, Na₂CO₃ powder is added in the last portions, after holding the solution-melt for 3 hours at T=1,100 °C and the temperature in the furnace is quickly lowered to (Tnas - 10) °C and then lowered slowly, at a speed of 3–4 °C/day, after 3 days the crucible is removed from the furnace and the solution-melt is drained, the grown single crystals in the form of black prisms are separated from the remnants of the solution-melt by etching in 20 % nitric acid solution.

EFFECT: technical result of the invention is to obtain Mn-Fe-containing magnetic material with a spin glass state with phase and chemical homogeneity.
