Abstract
The properties of the heavy-fermion superconductor Ce3PtIn11 are investigated by thermodynamic and transport measurements at ambient and under hydrostatic pressure. At ambient pressure the compound exhibits two successive magnetic transitions at T1≃2.2 K and TN≃2 K into antiferromagnetically ordered states and enters into a heavy-fermion superconducting phase below Tc≃0.32 K. The coexistence of long-range magnetic order and superconductivity is discussed in the context of the existence of the two crystallographically inequivalent Ce sites in the unit cell of Ce3PtIn11. The experimental data allow us to construct the pressure-temperature phase diagram.
