“…A second example of the use of the theory of the Kronecker products of corepresentations which we have already described lies in the determination of selection rules for various processes involving electrons, phonons or magnons in a magnetic crystal. This has been discussed by Cracknell(l967 b) and Fleury and Loudon (1968) for the MnF, structure, by Cracknell and Joshua (1969) for the NiO structure and by Begum et al (1969) for the NiF, structure.…”

When we calculated the spin-wave contribution to the specific heat of NiF2 recently (1, 2) only approximate values of the exchange constants J were available. Since then more accurate values of these exchange constants have become available (3) and so it seemed worthwhile to repeat the calculations using these new values.J2, and J3 1'Using the method employed previously we use the known values of the spin-wave energies at gether with the new values of J1, J , and J (see Table 1) to determine the re-2 3.k = 0 determined from antiferromagnetic resonance experiments toNew value (cm-l) (reference (3)) Table 1 15.5
