N2 - Solid solutions with the composition: TlCo2SxSe2-x (0.0 {slanted equal to or less-than} x {slanted equal to or less-than} 2.0), were synthesized by high temperature solid state reactions. Resistivity measurements on sintered pellets demonstrated that all of the compositions were highly metallic (ρ{variant} = 10-4 - 10-5 Ω-cm). The magnetic phase diagram was determined by magnetic susceptibility measurements. The Se-rich phases (0.0 {slanted equal to or less-than} x ≤ 0.75) order antiferromagnetically, the S-rich phases (0.75 ≤ x {slanted equal to or less-than} 2.0) order ferromagnetically, and the intermediate composition (x = 0.75) shows competition between antiferromagnetic and ferromagnetic behavior.
