EuTiO3 is an incipient ferroelectric antiferromagnet
showing an anomalously strong spin-phonon coupling. We studied
EuTiO3 ceramics by terahertz (THz) time-domain spectroscopy
upon varying temperature and magnetic field. We observed a
large anisotropy which is due to the shift from the microwave
to the sub-THz region of a ferromagnetic resonance appearing
only when the external magnetic field is applied perpendicular
to the magnetic component of the THz radiation.
