The magnetic structure of the Nd7Pd3 compound

DOI

The magnetic and electrical properties of R7Pd3 compounds [hexagonal Th7Fe3-type (hP20, P63mc)] were investigated in an earlier work. For Nd7Pd3 a ferromagnetic ground state was found with a TC = 33 K, followed by a further and faint antiferromagnetic transition at TN of about 38 K. However, for Nd7Pd3 a more recent work reported the presence of the ferromagnetic transition (with a TC = 34 K) but it did not confirm the antiferromagnetic ordering at the slightly higher temperature, thus apparently posing doubts about the second and latter transition. To study in more detail the magnetic behavior of Nd7Pd3 and clearly determine type and number of magnetic orderings, we have performed magnetization and heat capacity measurements. Low-field magnetization data show a weak antiferromagnetic-like anomaly at 38 K, followed, on cooling, by a well evident ferromagnetic transition at 34 K; the inverse susceptibility indicates a ferromagnetic ground state. The heat capacity measures, instead, clearly show two peaks (37.5 K and 34 K), with the low-T one likely associated to a first order transition.By neutron diffraction we plan to investigate the magnetic structure(s) of the Nd7Pd3 compound.
