Abstract
Cobalt Selenide is an important transition metal chalcogenide. It has been characterized by x-ray powder diffraction and low temperature magnetic studies in the temperature range 300K to 20K. The XRD study confirms the orthorhombic structure of the compound with lattice parameters a = 6.557±0.02A, b = 3.588±0.02 A and c = 5.200±0.02 A. The study of magnetic susceptibility gives the hints for cooperative interaction between the cobalt spins in the sample. The M-H curve confirms the ferromagnetic nature of the compound in the temperature range 20K to 300K. The saturation magnetization and retentivity are found to be almost constant. The application of magnetic field alongwith low temperature cause ordered spin orientation.Cobalt Selenide is an important transition metal chalcogenide.
