Oxygen vacancies in BaTiO3 based ferroelectrics: electron doping, history dependence of Tc and domain wall pinning
Francesco Cordero, Floriana Craciun, Paulo Sergio da Silva +3
We measured the complex Young's modulus of BaTiO3-d, BaxSr1-xTi3-d (BST) and Ba0.85Ca0.15Zr0.1Ti0.9O3-d (BCTZ) during heating and cooling runs at various O deficiencies and aging t…

Probing ferroelectricity in highly conducting materials through their elastic response: persistence of ferroelectricity in metallic BaTiO3-d
F. Cordero, F. Trequattrini, F. Craciun +3
The question whether ferroelectricity (FE) may coexist with a metallic or highly conducting state, or rather it must be suppressed by the screening from the free charges, is the fo…
