The present research aimed at creating the PIN junction in "ambipolar" cuprate systems, which was recently discovered in high-temperature cuprate superconductors. The PIN junction was not successfully created because of a difficulty to grow large single crystals of the "ambipolar" cuprate systems. However, as for the physical properties in the "ambipolar" cuprates, two important results are elucidated : One is the jump of the chemical potential, and the other is that the magnetic structure changes upon changing the sign of the charge carriers.

本研究旨在在“双极”铜塔系统中建立针连接，该系统最近在高温铜酸盐超导体中发现。引脚连接未能成功创建，因为难以生长“双极”铜塔系统的大型单晶。但是，至于“双极”铜岩中的物理特性，阐明了两个重要的结果：一个是化学电位的跳跃，另一个是磁性结构在改变电荷载体符号时会发生变化。
