Ba₂Y₁Cu₃O_xの焼結体の複素帯磁率より見た粒界の組織

抄録

The physical properties of grain boundary involved in a disk sample of sintered Ba₂Y₁Cu₃O_x has been studied in terms of complex susceptibility. It has been revealed that the superconducting transition of the sample takes place through the concurrence of the bulk and coupled phases.
