· Pr3 Co11 B4

Pr₃Co₁₁B₄ is an intermetallic compound combining praseodymium, cobalt, and boron, representing a research-phase material in the rare-earth transition-metal boride family. This compound is primarily of interest in fundamental materials science and magnetic applications research, where rare-earth intermetallics are explored for permanent magnets, magnetic refrigeration, and high-temperature magnetic devices; while not yet widely commercialized, materials in this family are investigated as alternatives or supplements to conventional rare-earth permanent magnets (NdFeB, SmCo) and cryogenic applications.
