Freeon waves

Freeon waves are detected in magnetic materials by neutron diffraction acting on the spin space. The frequency of the waves is observed to be... [Pg.29]

This is called the freeon-wave dispersion. It is expressed in terms of a lattice parameter, a, by the substitution... [Pg.29]

The coupling of the freeon waves with the appropriate spin function produces a wave function which has nonzero matrix elements with the wave function of a neutron scatterer so that permutation dispersion relation can be and has been experimentally verified. [Pg.30]

For p >1 more than one permutation wave state occurs in the same Cn-IRS and gives rise to freeon wave-fieeon wave interaction. [Pg.30]

In this, my third contribution, I apply freeon dynamics to problems of interest in chemistry and physics and compare with the results obtained by the spin paradigm. In particular I will apply freeon dynamics to the following "spin phenomena" i) spin exchange, ii) spin superexchange, iii) spin polarization, iii) spin density, iv) high-and low-spin states of the transition-metal ions, v) the periodic table, vi) ferromagnetism, vii) spin waves and viii) high-Tc superconductivity. [Pg.8]

Benzene played an important role in my development of freeon dynamics. I knew, by the Rumer rule, that benzene had five canonical structures (i. e., five linearly independent wave functions). These are the two Kekule structures and the three Dewar structures. From this I surmised that the singlet IRS for N = M = 6 should be of five dimensions. On consulting the symmetric group textbooks I... [Pg.23]

In Section 4.4 the freeon ferromagnetic Hamiltonian is used to the develop the freeon theory of spin-waves. [Pg.27]
