· JVASP-23827· YbCoB4

YbCoB4 is a rare-earth cobalt boride intermetallic compound combining ytterbium, cobalt, and boron. This is a research material studied primarily for its potential magnetic and electronic properties rather than a commercial engineering material; compounds in the rare-earth transition-metal boride family are investigated for applications requiring specialized magnetic behavior, hard coatings, or high-temperature phases, though YbCoB4 specifically remains in the experimental phase with limited industrial deployment.
