Bulk single crystals of SrPt3 P have been grown for the first time by a self-flux method at 2 GPa and 1500 °C using the cubic-anvil, high-pressure and high-temperature technique. The grown black crystals were found to have either a plate-like or pillar-like morphology with maximum dimensions of ~1×0.6×0.3 mm3. According to a goniometric study the crystals are elongated in the ab -plane with the c -axis perpendicular to the plane. The crystal structure was confirmed by X-ray diffraction (P 4/nmm , #129, Z =2, a =b =5.7927(2) Å, c =5.3729(2) Å and V=180.290(11) Å3). Temperature dependent susceptibility measurements showed a single-phase behaviour and a superconducting transition temperature of 8.6 K. This value for single crystals is slightly higher than that previously reported for polycrystalline SrPt3 P. The sharpness of the susceptibility drop (∆T c =0.07 K) supports a high homogeneity of obtained crystals.
