Domains visualization in NiO and BTO and strain mapping studies on defect rich complex oxides (STO and YAG)

This series of experiments on single crystal oxides was divided according to the goals: The study of NiO at high temperature aimed to complete previously acquired data on the visualization of K-domains and S-domains in NiO . The study on BTO aims for the visualization of Ferroelectric domains mapping the 111 or 222 Bragg reflection. This will allow simultaneous visualization of dislocations and domains constituting the first of a series of future experiments. Lastly several single crystals of doped STO and YAG will be scanned to validate the possibility to visualize the strain fields derived from single standing defects on the lattice in a systematic manner.
