Pressure phase diagram and quantum criticality of CePt₂In ₇ single crystals

We report the temperature-pressure (T-P) phase diagram of CePt ₂In₇ single crystals, especially the pressure evolution of the antiferromagnetic order and the emergence of superconductivity, which have been studied by electrical resistivity and ac calorimetry under nearly hydrostatic environments. Compared with its polycrystalline counterpart, bulk superconductivity coexists with antiferromagnetism in a much narrower pressure region. The possible existence of textured superconductivity and local quantum criticality also are observed in CePt₂In₇, exhibiting a remarkable similarity with CeRhIn₅.
