摘要:
The pinning energy due to the elastic interaction of a semicoherent Y2BaCuO5precipitate with the YBa2Cu3O7matrix is computed. This is achieved by setting up dislocation arrays at the interface. The elastic stresses generated by such arrays are integrated over a fluxoid volume to obtain the energy. It is seen that this elastic interaction energy makes an additive contribution to the totalJcvalue.
