Abstract

Millimeter-sized single crystals of Ln 6M 4Al 43 (Ln=Gd, Yb; M=Cr, Mo, W) were successfully grown with a molten aluminum flux. Synthetic conditions and physical properties for single crystals of all six analogs are discussed. The compounds exhibit metallic resistivity with room temperature values between 0.1 and 0.6 mΩ-cm. The Yb analogs are Pauli paramagnets with the Yb ion adopting the nonmagnetic divalent configuration (Yb 2). Gd 6Cr 4Al 43, Gd 6Mo 4Al 43, and Gd 6W 4Al 43 appear to order antiferromagnetically at 19, 15, and 15 K, respectively. © 2012 Elsevier Inc. All rights reserved.
