论文摘要
我们在Nowotny Chimney Ladder Compound Ru $ _2 $ sn $ _3 $的高质量单晶中介绍了磁层测量。我们发现线性且非饱和的磁磁性最高为20 t。磁磁性随磁场方向的变化，在小磁场处，从正曲率到负曲率。在5吨以上，对于任何测得的角度，磁势没有饱和的迹象最高20 t。当温度升高并遵守Kohler的规则时，磁化率中各向异性的形状仍然存在。我们将线性和非饱和磁磁性与热点相关联，这可能是由于结构过渡而形成的。我们讨论了在磁场下的电子 - 电子相互作用的相关性，以及在Ru $ _2 $ sn $ _3 $中预期的拓扑非平地属性的各个方面。
We present magnetoresistivity measurements in high-quality single crystals of the Nowotny chimney ladder compound Ru$_2$Sn$_3$. We find a linear and nonsaturating magnetoresistance up to 20 T. The magnetoresistance changes with the magnetic field orientation at small magnetic fields, from a positive to a negative curvature. Above 5 T, the magnetoresistance shows no sign of saturation up to 20 T for any measured angle. The shape of the anisotropy in the magnetoresistance remains when increasing temperature and Kohler's rule is obeyed. We associate the linear and nonsaturating magnetoresistance to a small Fermi surface with hot spots, possibly formed as a consequence of the structural transition. We discuss the relevance of electron-electron interactions under magnetic fields and aspects of the topologically nontrivial properties expected in Ru$_2$Sn$_3$.
