- Description
- Using Raman scatting excitations of phonon and magnetic origin are studied as function of temperature and magnetic field. Our aim is to search for effects of helical/conical and the Skyrmion phase on the excitation spectrum. We find interesting anomalies that are interpreted as four-chroism and anomalous magneto-dielectric coupling. Some of these effects have previously been predicted and experimentally observed in a limited energy regime in absorption experiments. .
