Research Abstract

Sub-pico scale atomic displacement contributing to electric polarization in multiferroic material of YMn2O5 has been detected. We developed the measurement program for avoiding “spurious" signal coming from multiple scattering, which enables to extract intrinsic signals in ferroelectric phase. We have found the order parameter of the ferroelectric displacement of which evolution follows the temperature dependence of the electric polarization.
