摘要

FIELD: nanotechnologies.;SUBSTANCE: invention relates to ordered photochromic ferromagnet arrays of nanowires on the basis of (tris)oxalates of transition meals and cations of spirocyclic row and may be used as light-sensitive magnetic nanomedia with supercapacious magnetooptic memory. The assigned task is solved by compounds in the form of derivative (tris)oxalates of transition metals and cations of spirocyclic row with general formula PCMe₁Me₂(C₂O₄)₃, where M₁, M₂ - 3d metals, PC - photochromic cations having photomagnet properties. Ordered arrays of nanowires of photochromic ferromagnets are produced by incorporation of above compounds into pores of the membrane from anodixed aluminium oxide (AOA), density of which makes 10¹¹-10¹³ cm^-2, and pore size is 20-200 nm. Ordered arrays of nanowires of photochromic ferromagnets are used as light-sensitive magnetic media for production of materials with supercapacious magnetooptic memory of up to 10¹³ bit/cm².;EFFECT: development of ordered arrays of nanostructures, in which elementary cells are nanowires of photochromic material with magnetic ordering.;3 cl, 6 dwg
