AC Hopping Conductance in Nanocomposite Films with Ferromagnetic Alloy Nanoparticles in a PbZrTiO3 Matrix

In this work, the temperature and frequency dependences of the real part of the admittance [ σ ( f ,  T )] of annealed nanocomposite films containing Co 45 Fe 45 Zr 10 -based nanoparticles covered with native oxides and embedded in a doped PbZrTiO 3 ferroelectric matrix were studied. The nanocomposi...

Description
Summary:In this work, the temperature and frequency dependences of the real part of the admittance [ σ ( f ,  T )] of annealed nanocomposite films containing Co 45 Fe 45 Zr 10 -based nanoparticles covered with native oxides and embedded in a doped PbZrTiO 3 ferroelectric matrix were studied. The nanocomposites studied were deposited by ion sputtering a complex target in a mixed Ar/O 2 atmosphere followed by a 15-min annealing process (with steps of 25 K) in air in the temperature range of 398 K ≤  T a  ≤ 573 K. The σ ( f ,  T ) of the annealed samples was measured in the temperature range of 77 K
