Extending interstitial tetrelides into carbides: synthesis and crystal and electronic structures- of RE₂Co₂AlC (RE = La, Pr, Nd)

Abstract

New quaternary compounds RE2Co2AlC (RE = La, Pr, Nd) of the filled W2CoB2 structure type were synthesized by the reaction of samples with nominal composition RE40Co40Al20 (RE = La, Pr,...

Heavy-Fermion Properties of Yb2Pd2SnH≈2

“…The R 2 T 2 X (R = rare-earth, T = transition metal, X = p-metal) series represents an extended group of materials, recently attracting lot of attention [1][2][3][4][5][6][7][8]. Although several different crystal structures have been identified for the given stoichiometry [9], most research effort has been focused on the family of tetragonal compounds with the Mo 2 FeB 2 structure (ordered ternary derivative of the U 3 Si 2 type).…”
