Growth and characterisation of PrCo2P2 and NdCo2P2 single crystals — •Benjamin Helmer, Fabian Fiedler, Kristin Kliemt, and Cornelius Krellner — Physikalisches Institut, Goethe-Universität Frankfurt, 60438 Frankfurt am Main, Germany
Recently, long-lived spin waves in the THz regime were discovered in the metallic antiferromagnet CeCo2P2 [1], resulting from an intricate interplay of structural and magnetic degrees of freedom in this compound. Therefore it is of current interest to investigate similar compounds in the LnCo2P2 series. Here, we present the crystal growth of (Pr,Nd)Co2P2 in tin flux, using temperatures of up to 1400∘C and a vertical temperature gradient, and the corresponding structural and physical characterization.
The structural characterization is performed by powder x-ray diffractometry, energy-dispersive x-ray spectroscopy and Laue diffraction. Magnetic properties of these systems, arising from the combination of the 4f-moments of (Pr,Nd)3+-ions and the 3d-moments of Co3+, are investigated by measurements of magnetization and heat capacity.
