A Kondo Lattice Antiferromagnet CePd5Al2

We report on the electrical resistivity, magnetic susceptibility and heat-capacity measurements on a new intermetallic compound CePd5Al2, crystallizing in the ZrNi2Al5-type tetragonal structure, with lattice parameters a = 4.156 A and c = 14.883 A. The compound presents Kondo lattice behavior and an easy-plane antiferromagnetic ground state with two magnetic transitions at 2.9 K and 3.9 K. The Sommerfeld coefficient is estimated as 60 mJ/mol K^2.

Single crystal flux growths of thermoelectric materials

We review recent achievements in single crystal flux growths for selected families of novel candidate materials for thermoelectric conversion applications, and the resulting contributions towards a better understanding of the physical mechanisms involved in optimizing their intrinsic thermoelectric figures of merit, ZT. We also take the opportunity to compile a small list of tips and tricks that we and other researchers have developed over the years to facilitate or optimize flux growths in general – those finer details that do not normally make it into mainstream research publications.
