· JVASP-10530· ThFe4P12

ThFe4P12 is a rare-earth intermetallic compound containing thorium, iron, and phosphorus in a 1:4:12 stoichiometric ratio. This material belongs to the family of skutterudite-related phases, which are primarily investigated for thermoelectric and quantum materials applications due to their unique crystal structure and electronic properties. ThFe4P12 remains largely a research compound, with potential utility in high-temperature thermoelectric generators, magnetocaloric devices, or fundamental condensed-matter physics studies exploring electron-phonon interactions and exotic ground states.
