Discovery of magnetic phase transitions in heavy-fermion superconductor CeRh $_{2}$ As $_{2}$

arXiv:2402.18763 · doi:10.1103/PhysRevLett.132.076504

Abstract

We report on the specific heat studies performed on a new generation of CeRh $_{2}$ As $_{2}$ single crystals. Superior quality of the samples and dedicated experimental protocol allowed us to observe an antiferromagnetic-like behavior in the normal state and to detect the first-order phase transition of magnetic origin within the superconducting state of the compound. Although in the available literature the physical behavior of CeRh $_{2}$ As $_{2}$ is most often described with the use of quadrupole density wave scenario, we propose an alternative explanation using analogies to antiferromagnetic heavy-fermion superconductors CeRhIn $_{5}$ and Ce $_{2}$ RhIn $_{8}$ .
