The heavy fermion systems present a unique platform in which strong electronic correlations give rise to a host of novel, and often competing, electronic and magnetic ground states. Amongst a number of potential experimental tools at our disposal, measurements of the Hall effect have emerged as a particularly important one in discerning the nature and evolution of the Fermi surfaces of these enigmatic metals. In this article, we present a comprehensive review of Hall effect measurements in the heavy fermion materials, and examine the success it has had in contributing to our current understanding of strongly correlated matter. Particular emphasis is placed on its utility in the investigation of quantum critical phenomena which are thought to drive many of the exotic electronic ground states in these systems. This is achieved by the description of measurements of the Hall effect across the putative zero-temperature instability in the archetypal heavy fermion metal YbRh2Si2. Using the CeMIn5 (with M=Co, Ir) family of systems as a paradigm, the influence of (antiferro-)magnetic fluctuations on the Hall effect is also illustrated. This is compared to prior Hall effect measurements in the cuprates and other strongly correlated systems to emphasize on the generality of the unusual magnetotransport in materials with non-Fermi liquid behavior.

重费米子金属中的霍尔效应

重费米子系统提供了一个独特的平台，在该平台中，强电子相关性产生了大量新颖且经常相互竞争的电子和磁基态。在我们可以使用的许多潜在实验工具中，霍尔效应的测量已成为辨别这些神秘金属费米面的性质和演化的一项特别重要的工具。在本文中，我们全面回顾了重费米子材料中的霍尔效应测量，并检查了它在促进我们目前对强相关物质的理解方面所取得的成功。特别强调它在研究量子临界现象中的效用，这些现象被认为是在这些系统中驱动许多奇异的电子基态。这是通过对原型重费米子金属 YbRh2Si2 中假定的零温度不稳定性的霍尔效应测量的描述来实现的。使用 CeMIn5（具有 M=Co、Ir）系列系统作为范例，还说明了（反铁）磁波动对霍尔效应的影响。这与之前在铜酸盐和其他强相关系统中的霍尔效应测量进行了比较，以强调具有非费米液体行为的材料中不寻常的磁传输的普遍性。
