Abstract
- We report on magnetization, specific heat and resistivity experiments on single crystals of the novel heavy Fermion compound Ce$_3$PdIn$_{11}$. At ambient pressure the compound exhibits two successive transitions at T$_{1}$ = 1.63 K and T$_{\mathrm {N}}$ = 1.49 K into incommensurate and commensurate local moment antiferromagnetic states, respectively, before becoming superconducting below T$_{\mathrm {c}}$ = 0.42 K. The large values of dB$_{\mathrm {c2}}$/dT and B$_{\mathrm {c2}}$ = 2.8 T imply that heavy quasiparticles form the Cooper pairs. Thus, Ce$_{3}$PdIn$_{11}$ is the first ambient pressure heavy Fermion superconductor where 4f electrons are simultaneously responsible for magnetic order and superconductivity.
