“…These samples, however, are not measurable by INS. NiO is very often used as a benchmark material to put to the test ab initio theories for the exchange coupling and spin wave spectrum of strongly correlated oxides [13][14][15][16][17][18][19]. Nonetheless, the experimental data regarding spin wave dispersions that can be found in the literature are quite scarce [10].…”

“…I n this section we extend our earlier work [3,4] on the symmetry properties of NiF2. I n particular we complete our studies by deriving the selection rules for magnonphonon interactions in NiF,.…”

“…I n this paper we extend our earlier work on the symmetry properties of K,NiF, [l, 21 and NiF, [3,4] and we refer the reader to these papers for the crystal structure, magnetic lattices, and Brillouin zones both above and below the respective N6el temperature TN.…”

“…Finally, where two symbols, such as NI3+, M4+, appear the two magnon dispersion curves are non-degenerate. I n a similar way the magnon symmetries have been determined in NiF, (Joshua and Cracknell 1969) and COO (Daniel and Cracknell 1969). T h e structure of paramagnetic NiF, is the same as that of paramagnetic MnF, and therefore it belongs to the grey space group P4,lmnml'.…”
