METHOD OF PRODUCING SAMARIUM-CONTAINING MAGNETIC SPIN GLASS MATERIAL Russian patent published in 2012 - IPC C04B35/40 H01L43/10 

FIELD: chemistry.

SUBSTANCE: invention relates to production of novel materials with a spin glass magnetic state - systems with a singular ground magnetic state, which can be useful in chemical and nuclear industry and for development of magnetic information technology. The method of producing samarium-containing magnetic spin glass magnetic material involves preparation of a mixture from Fe₂O₃, Sm₂O₃ and TiO₂ held at temperature of 105°C, moulding pellets under pressure of about 10 kbar and sintering said pellets using a solid-state reaction technique. Sintering is carried out in three steps: at the first step at temperature of 1200°C for 24 hours, at the second and third steps at temperature of 1250°C for 24 hours, while heating the furnace at a rate of 150 degrees per hour. After each synthesis step, the pellets are once more milled, pressed and put into the furnace.

EFFECT: obtaining material with a spin glass magnetic state.
