Antiferromagnetism in Gd2Ni2Cd

Structural, electric and magnetic measurements have been performed on the new rare earth intermetallic compound Gd2Ni2Cd. It crystallises in the Mn2B2Al-type structure (space group Cmmm) and undergoes an antiferromagnetic transition at 65 K. Above 70 K the compound follows the Curie-Weiss law with μ = 8.03 μB and θ = + 22 K. The transition is confirmed by magnetoresistance data at 5 K in applied fields up to 9 T. Magnetization measurements at 5 K up to 5.5 T give evidence of a spin-flop transition at 1.5 T.
