Discovery of magnetic phase transitions in heavy-fermion superconductor CeRhAs
arXiv:2402.18763 · doi:10.1103/PhysRevLett.132.076504
Abstract
We report on the specific heat studies performed on a new generation of CeRhAs 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 CeRhAs 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 and CeRhIn.
