Nonlinear Optics Group
Nonlinear optical techniques like second harmonic generation are especially sensitive to the symmetry properties of matter. Therefore nonlinear optics are predestinated to study all kinds of ferroic and multiferroic ordering which always goes along with distinct changes in symmetry. In our research group we apply nonlinear optical techniques to study
- phase transitions in ferroics and multiferroics
- magnetoelectric coupling effects
- ferroic domain topographies
- dynamic properties of magnetic and ferrolectric ordering
