Crystal Structure and Magnetic Susceptibility of Ce₈Pd₂₄Sb

Zr2Ir6B with an eightfold superstructure of the cubic perovskite-like boride ZrIr3B0.5: Synthesis, crystal structure and bonding analysis

“…These findings indicate that the structures of these non-stoichiometric perovskite borides are actually only the average structures. Even in CePd 3 B 0.13 the eithfold superstructure (Ce 8 Pd 24 Sb-type [15]) found in related Ce 8 Pd 24 M (8xCePd 3 M 0.13 ) phases (M = Al, Ga, In, Ge, Sn, Pb), was not observed [16]. ZrIr 3 B x (0 oxr0.5) synthesized in the late 1970s make no exception as it was structurally described also as a simple cubic perovskite [10].…”

Magnetic ordering of the Mn sublattice: Dense Kondo-lattice behavior of Ce in(RPd3)8MnSingh1, Dhar2 2003Phys. Rev. B7000View full textAdd to dashboardCite

“…The relatively higher ρ in (CePd 3 ) 8 Mn arises from the incoherent Kondo spin disorder scattering. The peak at 16 K is not due to any phase transition as both the heat capacity (see below) and magnetization data do not show any anomaly at that temperature, but it is due to the transition from the incoherent to coherent Kondo scattering regime as seen, for example, in archetypal Kondo lattice compounds CeAl 3 , CeCu 6 27 and also in Kondo lattice antiferromagnet (CePd 3 ) 8 M (M = Ga, Ge and Al) 7,8,12 . The resistivity does not apparently exhibit any anomaly at T C ∼ The heat capacity of (CePd 3 ) 8 Mn though comparable to that of the La analogue is however larger in the entire temperature range of 1.5 K to 60 K. This is understandable as the predominant (at higher temperatures) lattice contribution will be nearly similar in the two compounds (the atomic masses of La and Ce differ by less than 1 %) but there will be an additional 4f-derived contribution, C 4f due to the Ce-ions in (CePd 3 ) 8 Mn.…”

Reduced moment magnetic ordering in a Kondo lattice compound: Ce8Pd24Ga

“…A number of recent discoveries have led to the resurgence of interest in the properties of the binary compounds which crystallise in the well known cubic Cu 3 Au-type structure. [1][2][3][4] Among these, CeIn 3 and CePd 3 exhibit interesting properties.…”

“…CeIn 3 shows antiferromagnetic ordering with T N = 10 K at ambient pressure, and becomes superconducting with T C =0.175 K at a pressure of 2.55 GPa. 1 On the other hand CePd 3 is a canonical intermediate valence compound which has been extensively investigated using many experimental techniques.…”
