Abstract

The physical origin of the mechanism of the formation of ferromagnetic ordering in carbon nanotubes (NTs), which were produced by means of high energy ion beam modification of diamond single crystals in 〈110〉 and 〈111〉 directions, has been found. It is concluded from analysis of experimental results on ferromagnetic spin wave resonance observed, that the only π-electronic subsystem of given NTs is responsible for the appearance of ferromagnetism. It is determined by asymmetry in spin density distribution in Su–Schrieffer–Heeger (SSH) topological soliton lattice. The formation of SSH topological soliton lattice is considered within the frames of 1D quantum Fermi liquid model (generalized SSH-model of conjugated organic conductors).
