Abstract
The magnetic behavior of the binary systems Co−Se and Ni−Se was investigated within the temperature region from 100 to 300 K. Both phases Co1−x Se and CoSe2 behave like antiferromagnetics following theCurie-Weiss law with magnetic moments between 2.22 and 3.16 μB. For the corresponding phases Ni1−x Se and NiSe2 the results indicate a feeblePauli paramagnetism. For some alloys a slight positive temperature coefficient could be observed.
Three quasibinary sections of the ternary phase (Co1−y Ni y )1−x Se and one section of (Co1−y Ni y )Se2 were investigated in the ternary system Co−Ni−Se. For all sections the increase of the Ni-content resulted in a continuous shift fromCurie-Weiss behavior toPauli paramagnetism. Due to the change from negative to positive temperature coefficients some ternary alloys have a temperature-invariant paramagnetism.
