“…The resistivity shows a weak negative magnetoresistance below 10 K, suggesting that the spin disorder scattering that originated from additional magnetic impurities is reduced by the application of a magnetic field. 12) In the present study of EuPd 3 , on the other hand, we observed a very weak negative magnetoresistance at 1.4 K, as shown in Fig. 2.…”

“…Recently, Pandey et al have reported a very similar behavior of ðTÞ of the nonmagnetic reference compound YPd 3 , where ðTÞ produces a shallow minimum at 14 K and increases slightly with decreasing temperature. 12) Since the ðTÞ data below 14 K scales with Àln T, Pandey et al suggested a Kondo-like behavior, and hence the presence of a low percentage of magnetic impurities in the sample. Interestingly, this resistivity minimum disappeared by applying a magnetic field.…”

“…The overall data of the electrical resistivity can be well fitted by the calculated curve, although a very small deviation is observed at approximately 100 K. As already mentioned in Sect. 3, Pandey et al reported the electrical resistivity of the nonmagnetic reference compound YPd 3 in the temperature range between 2 and 300 K. 12) The residual resistivity and the resistivity at room temperature were 0 ¼ 16 µ³0cm and RT ' 24 ³0cm, respectively. When the ðTÞ data of YPd 3 are normalized to those of EuPd 3 shown in Fig.…”

Contribution of J-Multiplet Levels to the Physical Properties of EuPd₃ with the Trivalent Electronic State

EuPd 3 is one of the few Eu intermetallic compounds with the trivalent electronic state of the Eu ion. We succeeded in growing single crystals of EuPd 3 by the Bridgeman method, and studied the electronic, thermal, and magnetic properties by measuring the electrical resistivity, specific heat, thermal expansion, magnetic susceptibility, and magnetization. The observed temperature dependences of the magnetic susceptibility in the temperature range between 2 and 800 K and of specific heat up to 150 K are analyzed by considering the contribution of the J-multiplet levels 7 F J with J = 0-6. Since the ground-state J-multiplet 7 F 0 is a singlet for the trivalent Eu ion, the magnetic susceptibility is due mainly to the mixing of the excited J-multiplet levels to the ground state by applying a magnetic field. The observed magnetic susceptibility can be explained by considering the mixing of the J-multiplet levels with J = 0-4. In addition, the specific heat data are well analyzed using the same J-multiplet levels with J = 0-2, showing a large specific heat contribution due to the J-multiplet levels even below room temperature. The excited levels with larger J values are located at much higher energies than the present experimental temperature range and irrelevant to the analyses.

“…Pd based metallic perovskite compounds RPd 3 B x C 1−x and binary RPd 3 have been recently studied by us [5−11]. These compounds crystallize in a simple cubic structure with Pm3m space group symmetry [6,10]. While the body center position remains vacant in RPd 3 [6,10], the same gets occupied by boron (and/or carbon) in RPd 3 B x C 1−x [6].…”

“…These compounds crystallize in a simple cubic structure with Pm3m space group symmetry [6,10]. While the body center position remains vacant in RPd 3 [6,10], the same gets occupied by boron (and/or carbon) in RPd 3 B x C 1−x [6]. Although, in most of the cases the introduction of boron in the lattice of parent RPd 3 compounds does not alter the crystal symmetries, it leads to a lattice expansion as well as a significant modification of the electronicstructure near the Fermi-level [6].…”

Abstract.We report the study of magnetic and transport properties of binary intermetallic compounds RPd3 (R: Tb and Er) and boron-filled perovskite compounds RPd3B. Our results suggest that the magnetic and transport behavior of boron-filled compositions is substantially different compared to that of undoped compounds. For example, TbPd3 and ErPd3 exhibit negative magnetoresistance, while boron-filled TbPd3B and ErPd3B shows positive magnetoresistance. In addition, our results also suggest that there exists a strong correlation between magnetic and electrical-transport behavior of these systems.

Magnetic properties D 9000Magnetic Behavior of Binary Intermetallic Compound YPd3. -The title compound, a possible hydrogen storage material, is characterized by powder XRD and magnetic and electrical resistivity measurements. YPd3 crystallizes in the cubic space group Pm3m in a well-defined ordered crystal lattice, free from any detectable impurity phase. It shows predominant diamagnetic behavior at high magnetic fields. However, the compound exhibits anomalous magnetic behavior at low fields. -(PANDEY, A.; MAZUMDAR*, C.; RANGANATHAN, R.; J.
