Paramagnetic Properties of Rare Earth Hydroxides, Oxalates, and Dibutyl Phosphates.

ABSTRACT: Magnetic separations present a promising approach for the recovery of rare earth (RE) elements from mixtures, particularly when coupled with precipitation techniques that enhance process efficiency and selectivity. However, the magnetic properties of RE materials typically encountered in the separations industry are not well characterized. Here, we synthesized a series of RE materials, combining four REspraseodymium (Pr), neodymium (Nd), terbium (Tb), and dysprosium (Dy)with three precipitating agentshydroxide, oxalate, and dibutyl phosphate. All materials showed typical paramagnetic behavior consistent with the Curie-Weiss law. At low temperatures, we observed weak antiferromagnetic correlations, which were more pronounced for the lighter RE ions (Pr, Nd). Particle morphology and cryst
