  We report the temperature-pressure (T-P) phase diagram of CePt2In7 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.
