Crystal Growth with Flux Method and Characterization of CeRu₂P₂ — •Fabian Feldmann, Kristin Kliemt, and Cornelius Krellner — Physikalisches Inst., Goethe Univ., DE

CeRu₂P₂ is a rare-earth ternary phosphide with the tetragonal ThCr₂Si₂ type crystal structure. The electrical resistivity in [100] direction of CeRu₂P₂ shows a broad maximum at T = 180 K and metallic behavior for lower temperatures [1], indicative of a slightly intermediate valent system, which was confirmed recently in RIXS measurements [2]. Here, we report a crystal growth method for CeRu₂P₂. The single crystals have been grown in Sn-flux with temperatures up to 1500 ^∘C. We have characterized the grown crystals with EDX and powder x-ray diffraction measurements. Furthermore, we present measurements of electrical resistivity, specific heat and magnetic susceptibility.
