Uranium monosulfide (US) is an inorganic chemical compound of uranium and sulfur.[2] It is produced by combining uranium metal powder with hydrogen sulfide to form uranium disulfide, followed by sulfur loss during high-temperature, vacuum annealing.[3]
Magnetically, the compound is paramagnetic at room temperature, with a Curie Temperature of 180 K.[4] It has the largest known magnetocrystalline anisotropy of any cubic system.[5]
