Holmium monosulfide is a binary inorganic compound of holmium and sulfur with the chemical formula HoS.[1][2]

Synthesis

[edit]

Heating stoichiometric amounts of pure substances in an inert atmosphere:

Ho + S → HoS

Physical properties

[edit]

Holmium monosulfide forms crystals of cubic system, space group Fm3m, unit cell parameter a = 0.5465 nm, Z = 4, isomorphous with NaCl.[3]

Uses

[edit]

HoS is an attractive material for potential application in electronic and magnetic recording devices.[4]
