The focus of this thesis is the investigation of the lattice dynamics and the coupling of magnetism and phonons in two different multiferroic model systems. The first system, which constitutes the main part in this work is the system of multiferroic

We investigate the long time behavior of waves in crystals. Starting from a linear wave equation on a discrete lattice with periodicity $\varepsilon>0$, we derive the continuum limit equation for time scales of order $\varepsilon^{-2}$. The effective

As non-toxic and sustainable materials the system of binary oxide semiconductors Cu2O, Cu4O3, and CuO is in the focus of current research, e.g., for solar-cell applications. The objective of this work is to analyse the vibrational and Raman spectrosc

After the discovery of high temperature (high Tc) superconductivity in copper oxide-based materials (cuprates) in 1986, this phenomenon was a unique property of the cuprates for more than 20 years. The origin of high Tc superconductivity is still und

In der vorliegenden Arbeit wird die Gitterdynamik der Hochtemperatursupraleiter (HTSL) La_{2}CuO_{4}, Bi_{2}Sr_{2}CuO_{6} und Bi_{2}Sr_{2}CaCu_{2}O_{8} untersucht. Weiterhin wird der zu La_{2}CuO_{4} isostrukturelle Isolator La_{2}NiO_{4} betrachtet.
