| Abstract: | The composition range of the ternary body-centered tetragonal phase (Co
x
Ni1–x
)11Se8 extends fromx=0.03 tox=0.37 at 580°C. The magnetic susceptibilities and their variation with temperature and composition were investigated within the temperature range from 100 to 300 K using a magnetic balance. The temperature dependence of the magnetic suceptibilities was found to be consistent with theCurie-Weiss law from which magnetic moments were derived. Assuming the magnetic moments as spin-only values each cobalt atom contributes two unpaired electrons. Change in composition did not affect the magnitude of the magnetic moments. Based on crystallographic and magnetic data a simple model for the mutual distribution of cobalt and nickel atoms could be constructed.
