Description

Изобретение относитс  к температурноЬтабильным ферритам с пр моугольной петлей гистерезиса, используемым дл  запоминающих устройств электронных вычислительных машин. Известный магнитный материал, предста л ющий со.бой литиймарганцевый феррит, содержит (в мол %): окись железа 73,3; окись магни  0,3; окись лити  14,1; окис марганца 6,3; окись висмута 4; фтористый натри  О,5. С целью уменьшени  времени перемагни чивани  в предложенный магнитный материал введены двуокись циркони  и фторис- тый литий при следующем соотношении меж ду компонентами (в вес.%): Сжись лити 3-4 Окись марганца2-6 Окись висмута2-5 фтористый литий0,2-0,6 Двуокись циркони 1-5 Окись железаОстальное Показатели предложенного материала: Управл ющий ток, ма1О5О Врем  перемагничивани , мк сек0.18 Температурный коэффициент коэрцитивной силы, %/ос0,2 Отношение разрушающего импульса к перемагничиваюшему0 .6 ормула изобретени  Магнитный материал, содержащий окисжелеза , висмута, лити  и марганца, личающийс  тем, что, с цеуменьшени  времени перемагничивани , его введены двуокись ииркоии    фтотый литий при следующем cooTHOmeHHir. пу компонентами (в вес.%): Сйсись лити 3-4 Окись марганца2-6 Осись висмута2-5 фтористый литий0,2-0,6 Двуокись циркони 1-5 Сжись железаОстальное.The invention relates to temperature-stable ferrites with a rectangular hysteresis loop used for electronic computer storage devices. The known magnetic material representing lithium-manganese ferrite, contains (in mol%): iron oxide 73.3; magnesium oxide 0.3; lithium oxide 14.1; manganese oxide 6.3; bismuth oxide 4; sodium fluoride Oh, 5. In order to reduce the magnetization reversal time, zirconium dioxide and fluoride lithium were introduced into the proposed magnetic material in the following ratio between the components (in wt.%): Sieve lithium 3-4 Manganese oxide2-6 Bismuth oxide2-5 lithium fluoride0.2-0 , 6 Zirconium dioxide 1-5 Iron oxide Ostalous Indicators of the proposed material: Control current, ma1O5O Remagnetization time, mk sec0.18 Temperature coefficient of coercive force,% / os0.2 Ratio of destructive impulse to remagnetizing .6 Invention formula Magnetic material containing okiszheleza, bismuth, lithium and manganese, lichayuschiys that, with time tseumensheni magnetization reversal, it dioxide introduced iirkoii ftoty lithium next cooTHOmeHHir.
