Study of the Electrical Conduction Mechanism in Low-Frequency Field for CuMnO₂ Crednerite-Type Materials Obtained by Microwave-Assisted Hydrothermal Synthesis

The electrical conductivity of nanocrystalline CuMnO₂ samples, obtained by microwave-assisted hydrothermal synthesis (MWH), is studied by impedance spectroscopy over a frequency range of 30 Hz to 2 MHz and a temperature range from 30 to 120 °C. Three samples are prepared to start from a m...
