Abstract We report a study of magnetization and transport properties such as electrical resistivity, thermal conductivity, and thermal Hall conductivity in high fields and at low temperatures for ZrSiS single crystals. Here, we find that the thermal conductivity ( κ x x / T ) is strongly suppressed in applied fields, having a good correlation with the large positive transverse magnetoresistance (TMR). The thermal Hall conductivity ( κ x y / T ) displays a sharp peak at extremely low field which reveals the high mobility of the electrons. In addition, the TMR displays clear Shubnikov de Haas (SdH) oscillation at low temperatures. Although the Zeeman splitting is obviously appeared in de Haas-van Alphen (dHvA) oscillation of the magnetization measurements and distinguished easily from the SdH oscillation. Negative longitudinal magnetoresistance (LMR) is also observed in ZrSiS which may be related to the chiral anomaly.

摘要 我们报告了 ZrSiS 单晶在高场和低温下的磁化和输运特性的研究，例如电阻率、热导率和热霍尔导率。在这里，我们发现热导率 ( κ xx / T ) 在外加场中受到强烈抑制，与大正横向磁阻 (TMR) 具有良好的相关性。热霍尔传导率 (κ xy / T ) 在极低的场中显示出一个尖峰，这表明电子的高迁移率。此外，TMR 在低温下显示出清晰的 Shubnikov de Haas (SdH) 振荡。尽管塞曼分裂明显出现在磁化测量的 de Haas-van Alphen (dHvA) 振荡中，并且很容易与 SdH 振荡区分开来。
