摘要

自发现高温超导以来，研究上临界场及其各向异性对于理解超导机制和指导应用至关重要。在此，我们使用定制的金刚石压砧 (DAC) 旋转器对Pr4Ni3O10单晶进行了原位高压角相关电输运测量，证实了其各向异性超导。各向异性参数约为1.6，随温度升高而降低，并在接近Tc时趋于1。通过比较铜氧化物和铁基超导体 (FeSCs) 的有效质量各向异性和嵌块间距，发现Pr4Ni3O10单晶超导体与双带模型一致，其中晶胞内的层内量子限制诱导了层间相干，从而导致三维 (3D) 超导。本研究不仅确立了块体Ruddlesden-Popper镍酸盐中各向异性超导的存在，还为维度在高温超导中的作用提供了关键见解。
