Abstract
The magnetization of alloys of neodymium with lanthanum has been measured from room temperature down to 1–5°K. Above about 15°K the susceptibility is field-independent and obeys a Curie-Weiss law modified by a small temperature-independent paramagnetic term, χ = C(T–θ) + K. The Curie constant C gives effective atomic moments for all alloys in approximate agreement with the theoretical value for the Nd3+ ion, 3–62 μBper atom. At lower temperatures the alloys show striking saturation effects, and it is suggested that this can be accounted for in terms of a model in which the magnetic interactions between neodymium atoms are anti-ferromagnetic for nearest neighbours but ferromagnetic for more distant neighbours.Keywords
