Holmium (Ho) is a rare-earth lanthanide metal prized for its exceptionally strong magnetic properties and high neutron absorption cross-section. It is used primarily in specialized applications requiring magnetic intensity or nuclear control, including permanent magnets for high-field applications, nuclear reactor control rods, and research-grade electromagnets. Engineers select holmium over common ferromagnets when extreme magnetic field strength or precise neutron moderation is critical, though its scarcity and cost limit adoption to niche, high-value applications.
