Description
Topological materials have many interesting properties and are the focus of intense theoretical and experimental research. The material PrAlGe has recently been predicted to be a Weyl semimetal with broken time reversal and inversion symmetries [1]. We present experimental results on various properties of PrAlGe single crystals such as magnetization, neutron diffraction, and electrical transport with a focus on the origin of the anomalous Hall and Nernst effects. This data is compared to theoretical calculations involving the Berry curvature of the Weyl nodes in the system.
