论文摘要

根据第一原理计算,评估了XMNP(X = Ti,Zr,Hf)化合物的异常霍尔(AHC)和异常的Nernst电导率(ANC),并还研究了通过更改磁化方向来调整此类性能的可能性。我们观察到,淋巴结线和小间隙区域对AHC和ANC的主要贡献是主要的贡献,在改变磁化方向时,AHC和ANC的显着变化源自整个Brillouin区域。我们的研究为可调横向热电应用的工程磁间化合物提供了有希望的线索。

Based on first-principles calculations, the anomalous Hall (AHC) and anomalous Nernst conductivities (ANC) of the XMnP (X=Ti, Zr, Hf) compounds were evaluated, and the possibility to tailor such properties by changing the magnetization directions was also investigated. We observed that nodal lines and small gap areas consist the dominant contributions to AHC and ANC, where the significant variations in AHC and ANC when altering the magnetization direction originate from the whole Brillouin zone. Our studies gave a promising clue on engineering magnetic intermetallic compounds for tunable transverse thermoelectric applications.
