STRUCTURE AND MAGNETIC PROPERTIES OF URANIUM OXYSULFIDE (UOS) (in French)
Journal Article
·
· Phys. Chem. Solids
UOS is tetragonal and antiferromagnetic with a Neel temperature T /sub N/ = 55 un. Concent 85% K and a paramagnetic Curie temperature be- / sub p/= 55DEK. In the antiferromagnetic region, there is a strong uniaxial anisotropy. Every uranium atom has a moment of about 2 s, directed along the c-axis. The interactions U--O-U are strongly negative. The succession of moments along c is + + - -. The magnetic unit cell is twice the chemical one along c. In the paramagnetic region, the inverse of the magnetic susceptibility vs temperature shows two linear portions with corresponding Curie constants C/sub 1/ = 0,9 (at low temperatures) and C/sub 2/ = 1,2 (at T> 450 un. Concent 85% K. (auth)
