Abstract

We report the superconducting phase diagram of PrOs₄Sb ₁₂ deduced from the real-part χ′ and the imaginary part χ″ of the AC susceptibility. The double transition at Tc1=1.85K and Tc2=1.75K seen in the specific heat may be related to features in χ′ and χ″, where full diamagnetic shielding is observed below Tc2 only. As function of magnetic field the phase bounded by Tc2 displays features reminiscent of the peak effect.
