✦ Synopsis

The magnetic properties of (Cr 1؊x Ni x ) 3 Te 4 with the pseudo-NiAs-type structure have been studied. The ferromagnetic transition temperatures for the compounds are found to decrease linearly with the substitution of Ni for Cr, from their magnetization measurements. At low temperatures below 80 K, the magnetization decreases with decreasing temperature; i.e., a weak antiferromagnetic component is superimposed on the ferromagnetism of the (Cr 1؊x Ni x ) 3 Te 4 compounds, and the NeH el temperature decreases with Ni substitution for Cr. When the magnetization was measured at higher magnetic 5eld or the sample was 5eld-cooled, this antiferromagnetic transition became ambiguous. The experimental results obtained were compared with those for (Cr 1؊x Fe x ) 3 Te 4 compounds.
