Direct evidence of electronic ferroelectricity in YbFe(2)O(4) using neutron diffraction and nonlinear spectroscopy
We report the first observation of room temperature spontaneous electric polarization in an electronic ferroelectric material, a YbFe(2)O(4) single crystal. The observation was based on second harmonic generation (SHG), a nonlinear optical process. Tensor analysis of the SHG signal revealed that thi...
