Изобретение относитс  к области химической технологии и касаетс  получени  магнитных моиокристаллических материалов.The invention relates to the field of chemical technology and relates to the preparation of magnetic myocrystalline materials.

Известна шихта дл  получени  монокристаллов с намагниченностью насыщени  1750гс.A known charge for producing single crystals with a saturation magnetization of 1750 s.

Однако дл  создани  ограничителей мощности с малым уровнем огран.ичен-и  требуютс  монокристаллы с более высоким, чем у иттрийжелезного граната значением иамагниценности насыщени  при сохранении узкой линии ферромагнитного резонанса.However, to create power limiters with a low level of cutoffs, single crystals with a higher saturation magnitude and magnitude magnitude than the yttrium iron garnet are required while maintaining a narrow ferromagnetic resonance line.

Цель изобретени  - разработка состава дл  выращивани  монокристаллов с общей формулой i|)3Fe5-xScxOi2 (при х не более 0,7), обладающих повышенной намагниченностью насыщени , узкой линией ферромагнитного резонанса .и высоким удельным электросопротивлением .The purpose of the invention is to develop a composition for growing single crystals with the general formula i |) 3Fe5-xScxOi2 (with x not more than 0.7), having an increased saturation magnetization, a narrow ferromagnetic resonance line and high electrical resistivity.

Это достигаетс  тем, что в «сходную шихту ввод т окись скаиди  при следующем соотношении компонентов, вес. %: а1з2Оз 6,19-6,18; РеаОз 13,48-13,12; ЗсгОз 0,94-1,26; РЬО 34,63-34,65; PbFg 44,76-44,79.This is achieved by the fact that scaidi oxide is introduced into the "similar mixture in the following ratio of components, weight. %: alz2Oz 6.19-6.18; ReaOz 13,48-13,12; ZsgOz 0,94-1,26; PbO 34.63-34.65; PbFg 44.76-44.79.

Пример. Шихту, содержашую, г: 2Оз 13,55; РеаОз 28,74; ЗсгОз 2,76; РЬО 75,89; РЬРз 98,08, перемешивают путем вибропомола , загружают в платиновый тигель емкостью 160 см, закрывают платиновой крышкой и помещают .в печь дл  выращивани  монокристаллов . Печь нагревают до 1300°С со скоростью по 150°/час, с выдержкой при 1300°С в течение 10 час. Раствор - расплав охлаждают до 1250°С со скоростью 5°С/час, до 1200°С 1°/час, до 1050°С 0,5°/час, до 950°С ,5°/час, а затем вместе с выключенной печью. Отделение кристаллов от застывшего расплава производ т путем длительного кип чени  в водном растворе азотной кислоты.Example. The mixture containing, g: 2Oz 13.55; ReaOz 28,74; CsgOz 2.76; PbO 75.89; Pyrz 98.08, stirred by vibrating milling, loaded into a 160 cm platinum crucible, closed with a platinum lid, and placed in an oven to grow single crystals. The furnace is heated to 1300 ° C at a rate of 150 ° / hour, with a holding time at 1300 ° C for 10 hours. The solution - melt is cooled to 1250 ° С at a rate of 5 ° С / hour, up to 1200 ° С 1 ° / hour, up to 1050 ° С 0.5 ° / hour, up to 950 ° С, 5 ° / hour, and then together with off the stove. The crystals are separated from the solidified melt by prolonged boiling in an aqueous solution of nitric acid.
