Zusammenfassung

The interplay among charge, spin and lattice degrees of freedom in solids gives rise to intriguing macroscopic quantum phenomena such as colossal magnetoresistance, multiferroicity and high-temperature superconductivity(1-3). Strong coupling or competition between various orders in these systems presents the key to manipulate their functional properties by means of external perturbations such as ...
