Abstract

Terahertz time-domain polarization measurement experiments probe the electomagnon excitations in an orthorhombic multiferroic YMn₂ O ₅. Spectral phase rotation function measured from the mutually orthogonal polarization components of transmitted probe pulses sensitively resolves the electromagnon resonances which appear unresolvable in conventional transmission spectroscopy. The retrieved oscillator parameters based on electro-optic effects in a lossy birefringent material show good agreement with the previously reported Fourier transform infrared spectroscopy data.
