Phase transitions in NdNiPb and Nd(5)NiPb(3) Conference Paper

abstract

• We report magnetic and thermodynamic measurements for NdNiPb and Nd5 Ni Pb3. High-temperature Curie-Weiss fits yield effective moments per Nd of 3.59 B for NdNiPb and 3.70 B for Nd5 Ni Pb3. These are close to the Nd3+ ionic moment, 3.62 B, showing that Ni is nonmagnetic in both cases. For NdNiPb a peak seen in both the magnetization and specific heat at 3.5 K indicates an antiferromagnetic transition at that temperature. Specific heat measurements show this transition to be formed from crystal-field-split Nd magnetic levels, and a fit yields values for crystal field splitting. Nd5 Ni Pb3 exhibits two magnetic transitions, an antiferromagnetic transition at 42 K, and an apparently weak-ferromagnetic canting transition at 8 K. These are confirmed by specific heat measurements. M-H curves show metamagnetism at temperatures between the two magnetic transitions. 2008 American Institute of Physics.
