Infrared and terahertz studies of polar phonons and magnetodielectric effect in multiferroic Bi Fe O 3 ceramics

$\mathrm{Bi}\mathrm{Fe}{\mathrm{O}}_{3}$ ceramics were investigated by means of infrared reflectivity and time domain terahertz transmission spectroscopy at temperatures $20--950\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, and the magnetodielectric effect was studied at $10--300\phantom{\rule{0.3em}{0ex}...
