Title: Magnetism and the absence of superconductivity in the praseodymium–silicon system doped with carbon and boron

Abstract

We searched for new structural, magnetic and superconductivity phases in the Pr–Si system using high-pressure high-temperature and arc melting syntheses. Both high and low Si concentration areas of the phase diagram were explored. Although a similar approach in the La–Si system produced new stable superconducting phases, in the Pr–Si system we did not find any new superconductors. At low Si concentrations, the arc-melted samples were doped with C or B. It was found that addition of C gave rise to multiple previously unknown ferromagnetic phases. Furthermore, X-ray refinement of the undoped samples confirmed the existence of the so far elusive Pr3Si2 phase.
