Magnetic and ferroelectric properties of Zn and Mn co-doped BaTiO3 |
(a) Dielectric constants versus frequency and the inset shows the frequency variations of dielectric loss of different compositions and (b) the temperature dependences of the dielectric constants of samples in a temperature range from 30 °C to 170 °C at 1 kHz and the inset shows the temperature variations of dielectric loss of different concentrations. |
