摘要：

The Y3+/Ho3+, Y3+/Dy3+, and Dy3+/Ho3+ interdiffusion coefficients in the YBa2Cu3O7 - delta-HoBa2Cu3O7 - delta, YBa2Cu3O7 - delta-DyBa2Cu3O7 - delta, and DyBa2Cu3O7 - delta-HoBa2Cu3O7 - delta systems have been determined in air at a temperature of 1233 K by the Boltzmann-Matano method from the yttrium/holmium, yttrium/dysprosium, and dysprosium/holmium concentration profiles across the diffusion zone between two pellets of the high-T (c) superconductors. The composition dependences of the interdiffusion coefficients in the solid-solution systems are presented.
