Damping mechanism in the novel La 2 Mo 2 O 9 -based oxide-ion conductors

Fang, Q F; Wang, Xinmei; Zhang, Guishan; Yi, Zhiguo


In this paper, the microscopic diffusion mechanism of oxygen vacancies in the oxygen-ion conductors La2-xAxMo2O9 with A = Bi, K and x = 0-0.15 are studied by the low frequency internal friction measurements. An internal friction peak associated with the phase transition around 833 K and two relaxation peaks associated with the short-distance diffusion of oxygen vacancies were observed in all samples. With increasing K and Bi doping contents, the activation energies of both relaxation peaks...[Show more]
