· JVASP-10791· Tb2KCuS4

Tb2KCuS4 is an experimental ternary sulfide compound combining terbium, potassium, and copper in a mixed-metal sulfide framework. This material belongs to the family of rare-earth transition metal chalcogenides, which are primarily investigated in academic and research settings for their potential electronic, magnetic, and structural properties rather than established industrial production.
