Abstract

Solid solutions of TlCo_2-xNi_xS₂ (0 {slanted equal to or less-than} x {slanted equal to or less-than} 2.0) with the ThCr₂Si₂-type structure were prepared by high temperature solid state reaction. All of the samples are highly metallic (δ ∼ 10^-4-10^-5 Ω-cm). TlCo₂S₂ orders ferromagnetically at ∼ 152 K, and TlNi₂S₂ is Pauli paramagnetic. Substitution of Co by Ni in TlCo_2-xNi_xS₂ (0.05 {slanted equal to or less-than} x {slanted equal to or less-than} 1.25) results in antiferromagnetic behavior. The magnetic moments localized on the Co ions in TlCo₂S₂ have been found to be oriented parallel with the a crystallographic direction as determined by magnetic measurements on an oriented single crystal. The magnetic structure of TlCo_2-xNi_xS₂ and the possible role of Ni ions in the solid solutions is discussed.
