SPIN-GLASS MAGNETIC MATERIAL Russian patent published in 2014 - IPC C04B35/40 C04B35/462 

FIELD: chemistry.

SUBSTANCE: spin-glass magnetic material TbFeTi₂O₇ includes iron, titanium, oxygen and terbium with the following component ratio, wt %: Tb - 37.61; Fe - 13.22; Ti - 22.66; O - 26.51. The method of obtaining the terbium-containing spin-glass material includes the preparation of a charge from oxides Fe₂O₃, Tb₂O₃ and TiO₂, the formation of pills and their agglomeration in four stages, the maximal temperature of burning constitutes 1250°C.

EFFECT: obtaining a novel magnetic material with the condition of spin glass, with the absence of strongly neutron-absorbing elements.
