Avoidance of ferromagnetic quantum criticality in Kondo lattice CePd<sub>3</sub>S<sub>4</sub>

ORAL

Abstract

CePd3S4 has interplay between ferromagnetism (FM), quadrupolar order, and the Kondo effect at low temperatures. This material is notable for its FM transition temperature, which is much higher than the value expected from the de Gennes scaling of the heavier RPd3S4 compounds. This work presents a comprehensive study of the electrical transport and magnetic properties of CePd3S4 under high pressure to better understand the exotic quantum phenomena that may be exhibited by this material. Our findings show that the FM quantum criticality is avoided by a new magnetically ordered phase that is most likely antiferromagnetic that spans from ~ 7 GPa to ~ 11 GPa.
