Abstract

Not your usual superconductor Most superconductors have only one superconducting phase. Khim et al . measured the magnetic susceptibility of the heavy fermion material CeRh 2 As 2 to reveal the presence of two distinct superconducting phases, one of which emerges from the other when an external magnetic field is applied (see the Perspective by Pourret and Knebel). The researchers ascribe the unusual properties of CeRh 2 As 2 to its crystal structure, which is globally centrosymmetric but consists of noncentrosymmetric layers. —JS
