“…T~t TN (Dyson 1956;Bloch 1962Bloch , 1963, the magnon contribution to the specific heat comes mainly from magnons 0004-9506/84/030305$02.00 with wavevectors in the vicinity of k~0. In the simple theory of antiferromagnetic crystals based on the.…”

“…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.…”
