论文摘要
PDCOO $ _2 $具有高度导电和各向异性，是基本和技术应用的有希望的材料。最近，减少的PDCOO $ _2 $薄膜显示出在氢退火后表现出铁磁性。在这里，我们证明，当PDCOO $ _2 $薄膜被用作消除水的阴极时，围绕膜产生的氢会减少材料并导致异常霍尔效应（AHE）的出现。此外，我们证明了AHE信号的符号也可以通过电解过程更改。电解改造的PDCOO $ _2 $胶片可能打开了Spintronics应用程序的大门。
PdCoO$_2$, being highly conductive and anisotropic, is a promising material for fundamental and technological applications. Recently, reduced PdCoO$_2$ thin films were shown to exhibit ferromagnetism after hydrogen annealing. Here, we demonstrate that when PdCoO$_2$ film is used as a cathode for dissociation of water, hydrogen generated around the film reduces the material and leads to the emergence of anomalous Hall effect (AHE). Moreover, we demonstrate that the sign of the AHE signal can also be changed with the electrolytic process. Electrolytically-modified PdCoO$_2$ films may open a door to applications in spintronics.
