A neutron diffraction study of the crystallographic and magnetic structure of LuVO3

Abstract A study of the crystallographic and magnetic structure evolution of LuVO3 has been carried out from neutron powder diffraction data and magnetic susceptibility measurements. A few degrees below T N ≈107 K a crystallographic transition from orthorhombic (Pnma) to monoclinic (P21/n) takes place; the antiferromagnetic structure, stable down to 2.4 K , is given by the basis vectors (0,Ay,Fz) (Pnma setting; A = m 1 =− m 2 =− m 3 = m 4 ).
