Paramagnetic Crystalline Cobalt Selenide Materials via a Molecular Approach

Cobalt selenide materials in the form of powder and thin films have been successfully prepared through decomposition of cobalt (II) selenophosphinate compound. For thin films deposition, aerosol-assisted chemical vapor deposition process at atmospheric conditions was used to coat both glass and GaAs surfaces. Resulting materials were characterized by X-ray powder diffraction, scanning electron microscope and SQUID magnetometer. The magnetic studies conclusively showed paramagnetic behaviors within the materials.
