We report the discovery of pressure-induced superconductivity, with in the heavy-fermion antiferromagnet where superconductivity and magnetic order coexist over an extended pressure interval. A T-linear resistivity in the normal state, accessed by an applied magnetic field, does not appear to derive from the existence of a two-dimensional quantum-critical spin-density wave.
