Determination of magnetic and elastic properties of FeBO3by light scattering

Abstract
Brillouin back-scattering measurements on the weak ferromagnet FeBO3 (TN=348K) are reported in the temperature range 77-350K in magnetic field up to 6 kG for an incident wavelength of 514.5 nm. From the magnetic field and directional dependence of the magnon frequency, the Dzialoshinski-Moriya field HDM (1958, 1960) was obtained over the whole temperature range, and precise values were found for the three dominant exchange contributions. The full set of elastic constants is reported.
