MULTIMAGNON ABSORPTION IN MNF2-OPTICAL ABSORPTION SPECTRUM.
Abstract
The absorption spectrum of MnF2 at 4.2K in the 3900A region was measured in zero external fields and in high fields. Exciton lines with magnon sidebands are observed, accompanied by a large number of weak satellite lines. Results on the exciton and magnon absorptions are similar to those of McClure et al. The satellite lines are interpreted as being multi-magnon absorptions, and it is possible to fit the energy of all the absorptions with magnon energy data. One intense line classified as a four magnon absorption appears to show the expected magnetic field behaviour. The same method of classification is used to classify all the subsidiary lines in the 5400A region observed previously by Sell. (Author)
