Gd2Au2Cd: A Mo2 Fe B2 -type intermetallic with ferromagnetic ordering and spin glass anomalies

Abstract

The ternary intermetallic compound Gd2 Au2 Cd, synthesized by reaction of the elements via inductive melting, is studied for its structural and physical properties. Gd2 Au2 Cd crystallizes with the Mo2 Fe B2 type (an ordered derivative of U3 Si2 structure), space group P4 mbm. The magnetic measurements (ac and dc susceptibility) establish magnetic ordering (To) at 110 K and have been confirmed by both transport (resistivity ρ;) and calorimetric (heat capacity, C) measurements. ac susceptibility measurements indicate "spin-glass" type anomalies below To. The nature of magnetic ordering and the low-temperature behavior in this compound have been investigated in detail. © 2006 The American Physical Society.
