Recent research has highlighted the potentially beneficial impact of magnetic effects on the performance of thermoelectric materials.1 However, the mechanisms involved in such systems remain largely unexplored and a more fundamental investigation is required to elucidate the role of magnetic ions in the enhancement of the thermoelectric properties. Recently, Zintl phase materials have sparked interest as potential thermoelectric materials, combining good thermoelectric properties with lower cost and toxicity compared with current commercial thermoelectrics. In this study, we report the thermoelectric properties and low-temperature magnetic data of n-type and p-type Zintl materials doped with magnetic ions. The sample preparation involves various synthetic methods such as mechanical alloying in inert atmosphere, solid-state reaction and in-situ reaction via spark plasma sintering (SPS).
