What is Spin-Peierls transition in carbynoid conductors: infrared absorption study about?

The results of IR-studies in quasi-1D carbynoid films produced by dehydrohalogenation of poly(vinilidene fluoride) are in good agreement with the assumption that carbynoid films studied are generalized spin -Peierls conductors, the metal to insulator transition in which can be described in the frame of t-J model. Residual atoms of fluorine, hydrogen and atoms of main technological impurity oxygen in the form of various complexes in interchain space are suggested to be spin - (or joint spin - and electrical) conductivity dopants. Antiferroelectric spin wave resonance (AFESWR) being to be optical analogue of antiferromagnetic spin wave resonance has been identified for the first time. Electric spin-Peierls polaron lattice in C-C -bonds is proposed to be responsible for the observed AFESWR both in starting PWDF films and in carbynoid B-films (the samples with the least impurity content). Electric spin moment with pure imaginary value predicted by Dirac as early as 1928 was identified for the first time. Electric spin-Peierls polarons are proposed to be electric spin moment carriers. It has been established that topological solitons, earlier called spin-Peierls solitons (SPS), are simu
