· JVASP-14014· TbMnSi

TbMnSi is an intermetallic compound combining terbium, manganese, and silicon, belonging to the family of rare-earth transition-metal silicides. This material is primarily of research interest for magnetocaloric and magnetostructural applications, where the coupling between magnetic and structural properties is exploited for solid-state cooling and magnetic refrigeration technologies. The compound's notable combination of magnetic ordering and mechanical properties makes it a candidate for next-generation energy-efficient cooling systems, though it remains largely in the developmental stage with limited industrial production.
