Executive Summary :

Rare-earth chalcogenides Ln₃X₄, consisting of Ln as a rare-earth metal and X as a chalcogenide element, have been studied for their unique physical properties, including superconductivity, magnetic, and thermoelectric properties. These compounds, which lack an inversion center, exhibit antisymmetric spin-orbit coupling, allowing for the admixture of spin-singlet and spin-triplet pairing states within the same orbital channel. These compounds are also known for their efficient thermoelectric properties, with La₃Te₄ and Ce₃Te₄ being particularly effective.
