Magnetic field driven complex phase diagram of antiferromagnetic heavy-fermion superconductor Ce${}_3$PtIn${}_{11}$

Abstract

We present the results of our comprehensive investigation on the antiferromagnetic heavy-fermion superconductor Ce${}_3$PtIn${}_{11}$ carried out by means of electrical transport, heat capacity and ac magnetic susceptibility measurements, performed on single-crystalline specimens down to 50 mK in external magnetic fields up to 9~T. Our experimental results elucidate a complex magnetic field -- temperature phase diagram which contains both first- and second-order field-induced magnetic transitions and highlights the emergence of field stabilized phases. Remarkably, a prominent metamagnetic transition was found to occur at low temperatures and strong magnetic fields. In turn, the results obtained in the superconducting phase of Ce${}_3$PtIn${}_{11}$ corroborate an unconventional nature of Cooper pairs formed by heavy quasiparticles. The compound is an almost unique example of a heavy fermion system in which superconductivity may coexist microscopically with magnetically ordered state.
