at frequencies of 0.485–0.765 THz with a continuous-wave source and in the temperature
range of 30–350 K as a function of polarization angle. The fine splitting of spin-wave modes
that could be detected with our vector network analyzer-based spectrometer is shown to
depend on polarization angle. The crystal shows strong, temperature-dependent, linear
dichroism. The interference pattern produced in the sample slab revealed a huge …
