Die magnetische Suszeptibilität flüssiger Übergangsmetallegierungen

Investigations on the magnetic susceptibility of alloys of the transition metals Fe, Co and Ni with the normal metals Au, (Cu), Zn, Ga and Ge were performed in the liquid state over the whole concentration range. These alloys show complicated phase diagrams, so that in the solid state a systematic investigation over the whole concentration range is not possible. The results are discussed with the existing models for the transition metal rich side and for impurities of transition metal in normal metals. A connection between the susceptibility and the density of states has been found, which allows to explain the behaviour of the susceptibility over the whole concentration range. The measurements of the susceptibility give some information about shape and position of the density of states on alloying.
