純自旋電流在攜帶極少或甚至沒有電荷載子的情況下，可以更有效地傳遞的自旋角動量，因此最近自旋電子現象的探索和自旋電子學元件的研究與進展已經由利用自旋極化電流演變為純自旋電流。在本文中，我們的工作證明了自旋玻璃系統中的自旋漲落可以用來增強純自旋電流。此外，我們還發現樣品的形狀和去磁效應會強烈影響純自旋電流的行為。

A pure spin current can more efficiently deliver spin angular momentum with fewer or no charge carriers. Therefore, spintronic phenomena and devices have evolved from exploiting spin-polarized current to pure spin current. Here, we demonstrate spin fluctuations in the spin-glass system can enhance the pure spin current. Furthermore, we show that the shape of specimens and demagnetizing effects strongly influence the manipulation of pure spin current.
