  text: In the present study, the new ternary rare earth intermetallic compound PrNi6Si6
    has been investigated. This work completes the study of the RNi6Si6 series (R = rare
    earth). While the RNi6Si6 compounds for R = La and Ce adopt the CeNi6Si6-type
    (tP52, P4/nbm, No. 125), surprisingly PrNi6Si6 crystallizes in the YNi6Si6 prototype
    (tP52, P − 4b2, No. 117) as do all the heavier lanthanides (but Lu). The YNi6Si6-type
    and its homolog CeNi6Si6 are two tetragonal ordered derivative of the cubic NaZn13-type
    structure. Lattice parameters for PrNi6Si6 are a = 7.7846(1) Å, c = 11.2144(1)
    Å, with a unit cell volume, Vobs = 679.585(5) Å3. The temperature dependence of
    the inverse magnetic susceptibility χ−1(T) follows the Curie–Weiss law, with calculated
    values of the effective magnetic moment (µeff) and Weiss temperature (Θpm) of
    3.55 μB and − 4.5 K, respectively. While the observed µeff is very close to the
    theoretical value of 3.58 µB for the free Pr3+ ions, a negative value of the Weiss
    temperature suggests antiferromagnetic interactions in PrNi6Si6. Magnetization
    measurements confirm that PrNi₆Si₆ orders antiferromagnetically (AFM) below a
    Néel temperature (TN) of 9 K. The Ni atoms contribute negligibly to the magnetic
    properties of this phase. The specific heat of PrNi₆Si₆ is approximately 0.42
    J K  − 1  g − 1. Measurements of electric and thermal transport reveal that PrNi₆Si₆
    exhibits metallic behavior across a wide temperature range of 2–900 K, accompanied
    by a relatively low thermal conductivity of around 6 W K − 1 m − 1 at room temperature.
    Such properties, together with its high-temperature refractory behavior, make
    PrNi₆Si₆ worthy of consideration in technological applications where fairly good
    electrical conductivity should be accompanied by a limited thermal conductivity.

  text: The Seebeck coefficients, electrical resistivities, total thermal conductivities,
    and magnetization are reported for temperatures between 5 and 350 K for n-type
    Bi0.88Sb0.12 nano-composite alloys made by Ho-doping at the 0, 1, and 3 % atomic
    levels. The alloys were prepared using a dc hot-pressing method, and are shown
    to be single phase for both Ho contents with grain sizes on the average of 900
    nm. We find the parent compound has a maximum of ZT = 0.28 at 231 K, while doping
    1 % Ho increases the maximum ZT to 0.31 at 221 K and the 3 % doped sample suppresses
    the maximum ZT = 0.24 at a temperature of 260 K.
