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…
