Abstract: Elastic neutron scattering experiments on the pressure-induced ferromagnetic superconductor have been carried out under pressures P up to 1.6GPa at temperatures T down to 60mK, to study the correlation between superconductivity and ferromagnetism. No change was observed in ferromagnetic Bragg peak intensities nor a line width at through the superconducting transition temperature under and 1.25GPa, suggesting that the ferromagnetism is not affected by the onset of superconductivity under these two pressures.

Abstract: We have prepared single crystals of SmS under various conditions, and studied sample dependence on the specific heat and the electrical resistivity. Some samples exhibit a huge anomaly in the temperature dependence of the specific heat at low temperatures. We show that the anomaly can be ascribed to secondary phases and will give rise to a spurious term in the golden phase. [Copyright &y& Elsevier]
