MAGNETOOPTICAL ELEMENT Russian patent published in 1997 - IPC

FIELD: applied magnetooptics, devices based on magnetooptical Faraday effect. SUBSTANCE: invention can be used in industry in magnetooptical devices of type of flaw detectors, reading heads, spatial-time light modulators, switches, deflectors and other magnetooptical devices employing mechanism of motion of magnetization. Magnetooptical element is manufactured from ferrite-garnet and has at least one rare-earth fast-relaxing ion and corresponds to chemical formula R_xA_yFe_uM_vO₁₂., where A is nonmagnetic and/or slow- relaxing magnetic ion; M is nonmagnetic ion. Substitutes are as such x≅3,y≅3,и≅5,v≅3.. Ferrite-garnet has point of compensation of moment of pulse within temperature range where magnetic ordering takes place near which relation is realized, where M_s is summary magnetic moment of all slow-relaxing magnetic ions; M_f is summary magnetic moment of all fast-relaxing magnetic ions. EFFECT: increased stability of operational characteristics. 36 cl
