Abstract

Neodymium-doped gadolinium vanadate (Nd:GdVO4) is a popular laser material at room temperature. It has received limited attention for quantum technologies because of the linebroadening effects of disordered gadolinium spins in the host. Here we investigate the optical properties at temperatures below the 2.5 K Néel temperature, revealing narrow optical transitions. We demonstrate that rare earth ions in magnetic hosts give us a new way of observing the signs of magnetic g-factors. The interplay between the exchange and Zeeman interactions means that we see clear evidence of negative g-factors. These results provide a detailed spectroscopic foundation for Nd:GdVO4 and expand the understanding of its candidacy as a material for hybrid quantum systems.
