Magnetic properties of undoped Cu<sub>2</sub>O fine powders with magnetic impurities and/or cation vacancies
Fine powders of micron- and submicron-sized particles of undoped Cu(2)O semiconductor, with three different sizes and morphologies, have been synthesized by different chemical processes. These samples include nanospheres 200 nm in diameter, octahedra of size 1 µm and polyhedra of size 800 nm. They exhibit a wide spectrum of magnetic …
