摘要：
Anisotropic resistivity of a YBa2Cu3O7-delta Single crystal has been measured as a function of thermal cycling between 288 K and 1006 K in flowing oxygen and nitrogen gases. The hysteretic temperature dependent rho (c), rho (ab) and their ratio rho (c)/rho (ab) provide evidence of oxygen diffusion in and out of the crystal, the tetragonal to orthorhombic structural phase transition and the paramagnetic to antiferromagnetic phase transition.
