The physical origin of the mechanism of the formation of ferromagnetic ordering in carbon nanotubes (NTs) produced by high energy ion beam modification of diamond single crystals in $<{110}>$ and $<{111}>$ directions has been found. It is determined by asymmetry of spin density distribution of Su-Schrieffer-Heeger topological soliton lattice formed in 1D Fermi quantum liquid state of $\pi$-electronic subsystem of given NTs. The phenomenon of formation of antiferromagnetic ordering coexisting with superconductivity at room temperature in carbon NTs, produced by high energy ion beam modification of diamond single crystals in $<{100}>$ direction is discussed.
