Vn. Polupanov et al., INVESTIGATION OF IRON BORATE ON THE SUBMILLIMETER WAVES, International journal of infrared and millimeter waves, 16(6), 1995, pp. 1167-1172
Antiferromagnetic resonance (AFMR) in iron berate at the frequency of
300 GHz at the room temperature in weak (down to 0.1T) external magnet
ic field H has been studied. The loss in AFMR line increased or decrea
sed depending on the direction and magnitude of H. Such properties of
FeBO3 monocrystals allows to design undirectional and modulation devic
es.
