Crystal growth and characterization of CeCo2P2 and EuFe2P2 — •Thanh Duc Nguyen, Johannes Hellwig, Marius Peters, Kristin Kliemt, and Cornelius Krellner — Physikalisches Institut, Goethe-Universität Frankfurt, 60438 Frankfurt/Main, Germany
The ternary phosphides CeCo2P2 and EuFe2P2 are compounds that belong to the ’122’-systems crystallizing in the ThCr2Si2 structure type. CeCo2P2 is an antiferromagnet due to the ordering of cobalt atoms at TN = 440 K . EuFe2P2 is a ferromagnet due to the ordering of divalent europium atoms with a Curie temperature of TC = 27.5 K . We synthesized both compounds in tin-flux using either quartz or niobium ampoules . In this way, large platelet-like CeCo2P2 single crystals of several mm lateral size were created. For the europium system the crystals are smaller. Electrical transport measurements and a magnetic characterization were done for both compounds. In addition, CeCo2P2 is a candidate for the investigation of its surface states by ARPES.
