Abstract：The oxygen adsorption-desorption properties of RBa2Cu3O7-δ R = Gd, Er, Eu, Dy, Sm, Ho and Nd?nd Y1-χLaχBa2Cu3O7-δ (χ = 0.1, 0.5 and 1.0) were investigated from room temperature to 950 oC by thermogravimetry (TG). The results show that all samples will release oxygen with the increasing of temperature and the released oxygen can be absorbed back into the sample when temperature decreases. However, dependent on the rare earth element, the amount of the released oxygen is different for these samples. Moreover, in the temperature increasing and decreasing circle the repetition of oxygen adsorption-desorption is also different.
