Crystal growth and characterization of materials with the ThCr2Si2 structure type — •Susanna Rongstock, Ali Scherzad, Alexej Kraiker, Doan-My Tran, Sebastian Witt, Kristin Kliemt, and Cornelius Krellner — Physikalisches Institut, Goethe University Frankfurt, Germany

We present the single crystal growth of different intermetallic compounds within the LnT2Si2 family (with Ln = lanthanides and T = Rh, Ir), by employing a high-temperature metal-flux technique. The habitus of the obtained crystals is platelet like with the crystallographic c direction perpendicular to the surface [1]. The magnetic properties of these crystals were characterized by magnetization, heat-capacity, thermopower and resistivity measurements. These crystals form the materials basis for a thorough study of exciting surface properties by angle-resolved photoemission spectroscopy [2,3].
