| Popis: | CuO in nanocrystalline form (nano-CuO) was obtained by chemical route. These nano-CuO crystallites were incorporated in polyvinylidene fluoride (PVDF) to form nano-CuO/PVDF free-standing composite films containing varying amounts of nano-CuO by using sol-gel method. These films indicated ferromagnetism at room temperature. All the films were appropriately characterized. Magnetization was found to decrease with increase in temperature. The observed ferromagnetism in nano-CuO/PVDF samples could be due to possible interaction between magnon scatterings arising from the Cu2+ ions of nano-CuO particles when embedded in PVDF matrix which in turn would alter the electronic configuration of Cu ions for inducing ferromagnetic property in these films under study. |
