Abstract: We investigate phase transitions of a geometrically frustrated polar magnet ${\mathrm{CaBaCo}}_{4}{\mathrm{O}}_{7}$, which exhibits the largest magnetoelectric (ME) effect in multiferroic compounds reported so far. Measurements of magnetization, sound velocity, and neutron diffraction of single crystals…

Abstract: We report the polarization rotation of terahertz light resonant with the magnetoelectric (ME) spin excitation in the multiferroic (Fe,Zn)_{2}Mo_{3}O_{8}. This resonance reflects the frequency dispersion of the diagonal ME susceptibility (axion term), with which we…
