Sažetak
The Al-Pd-Mn system of intermetallics contains complex metallic alloy (CMA) phases, whose crystal structures are based on giant unit cells comprising up to more than a thousand atoms per cell. We performed investigation of the magnetic, electrical and thermal transport and thermoelectric properties of the .' phase and the related 0 phase on single-crystalline samples. The samples are diamagnets with a tiny paramagnetic Curie-like magnetization and an estimated fraction of magnetic Mn atoms about 100 ppm. The electrical resistivity between 300 and 4 K exhibits a temperature variation of less than 2 %. The thermal conductivity of the samples is small and exhibits thermally activated behavior above 100 K, compatible with the excitation of localized lattice vibrations. The thermoelectric power is small and negative, compatible with a low concentration of electrons as the majority charge carriers.
