Crystal Growth of Materials with the ThCr2Si2 Structure Type

Abstract

The single crystal growth of 19 different intermetallic compounds within the LnT2X2 family (with Ln = lanthanides, T = Co, Ru, Rh, Ir, and X = Si, P) is presented, 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 and with individual masses between 1 and 100 mg. The magnetic properties of these crystals are characterized by magnetization, heat-capacity, and resistivity measurements. These crystals form the materials basis for a thorough study of exciting surface properties by angle-resolved photoemission spectroscopy.
