For a long time, spin–orbit coupling in bismuthates has been considered to be negligible; however, giant charge-to-spin conversion has now been observed in Ba(Pb,Bi)O3-based heterostructures. These observations provide a path toward investigating the interplay of hidden spin–orbit phenomena and superconductivity.

氧化物超导体正常状态下意外的大自旋电流


长期以来，铋酸盐中的自旋轨道耦合被认为可以忽略不计。然而，现在在 Ba(Pb,Bi)O3 基异质结构中观察到了巨大的电荷-自旋转换。这些观察结果为研究隐藏的自旋轨道现象和超导性的相互作用提供了一条途径。
