The magnetic phase diagram of a single crystal CeGaGe

Given the interest in topologically protected electronic states for next generation technologies, there is a considerable interest in new materials that may host such states and that also feature magnetic moments where interplay between topological electrons and magnetic moments can be studied and perhaps manipulated. With this motivation, we have grown single crystals of the semimetal CeGaGe [1] using the floating zone method, and the crystal structure suggests that it may host protected Weyl nodes, in analogy to several other structurally related materials [2,3]. We find that the material orders magnetically in zero field at 4.65 K. Here, we present the magnetic field-temperature magnetic phase diagram of single crystal CeGaGe and will discuss the potential for topologically protected states in the material.
