Highlights
Since being discovered in the early 1980s,1–3 Remeikaphase compoundstin-rich rare-earth transition-metal stannideshave attracted much attention, especially because of the coexistence of magnetism and superconductivity that is observed in some members of this family of compounds.[4]
We have found that a quaternary compound with the approximate chemical composition Yb5Pt6In16Bi2 is closely related structurally to the stannide phase Tb5Rh6Sn18
There is evidence from both thermodynamic and transport measurements of effects attributable to a crystal-field splitting of the trivalent Yb Jϭ7/2 Hund’s rule ground state
Summary
Structure and physical properties of the quaternary Remeika-phase compound Yb5Pt6In16Bi2. In addition to structural/composition studies identifying the compound as Yb5Pt6In16Bi2, we have made dc and ac magnetic susceptibility, specific heat, resistivity, magnetoresistance, Hall effect, and thermoelectric power measurements on this material. It appears that this Remeika-phase compoundstructure type Tb5Rh6Sn18) is moderately disordered. Crystal-field effects influence the temperature dependence of the dc magnetic susceptibility, the specific heat, the resistivity, and the thermoelectric power. A cusp in the ac magnetic susceptibility peaks near 300 mK, close in temperature to where the specific heat divided by temperature Cp(T)/T reaches a maximum. The susceptibility feature is frequency dependent and suggestive of a disorder-induced spin-glass transition rather than conventional magnetic order. ͓S0163-1829͑99͒03830-8͔
