· JVASP-53410· Tm2MnS4

Tm2MnS4 is a ternary sulfide compound combining thulium (a rare-earth element), manganese, and sulfur, belonging to the metal chalcogenide family. This is primarily a research material studied for its potential magnetic and electronic properties rather than a widely commercialized industrial material. Research interest focuses on its possible applications in magnetic semiconductors, solid-state device physics, and materials systems where rare-earth-manganese interactions at the sulfide interface could enable novel functionality.
