| Abstract: | This is a report of an X-band electronic paramagnetic resonance (EPR) study of Zn1−x Co x O (x = 1 and 3%) powders at various temperatures (10–200 K). EPR spectroscopy is a powerful tool to study the complex magnetic state and the Co ionic state, their local environment and interactions as well. These samples are interesting to study in order to understand how ‘Co doping’ produces ferromagnetism in ZnO2, making it a promising ferromagnetic semiconductor at room temperature. |
