Capacitive properties of nanocomposite (FeCoZr)_x(PZT)_(100-x) produced by sputtering with the use of argon and oxygen ions beam

摘要

The paper established that, the hopping mechanism of the charge exchange for the (FeCoZr)_(64.4)(PZT)_(35.6) nanocomposite and the additional polarization of tested sample occurs. As frequency increases two frequency areas where capacitance decreases can be observed. Correlation between the conductivity increase and the capacitance decrease has been observed for the both stages of their variability. Voltage resonance phenomenon for the studied material was observed. The zero crossing in the frequency dependence of phase difference transition is accompanied with this phenomenon, which is reflected by a sharp minimum in the capacitance versus frequency characteristics.
