| Research Abstract |
Instead of using cavity resonator, a newly-designed electromagnetic horn type ESR spectrometer, adopting the electromagnetic horn antennas as a sample cell, was constructed. The merit of horn type ESR is to provide an experimental flexibility in comparison with the closed and small space in past cavity resonator, and Q value free. We have applied it to extreme state specimens such as ferroelectric and ferroelastic crystal, when the ferroic phase transition or domain switching phenomenon occurs.
