Effect of magnetic ion doping on structural, electric and relaxor properties of Pb (Fe2/3W1/3) O3 multiferroic ceramics

“…In despite of this, here we present in Figure 4, for better visualization, the curves with adjusted parameter in all temperature interval. The dot curves in Figure 4 corresponds to the best fit of the experimental results using Equation 3. The values for T C _ε ,δ and γ are presented in Table 2.…”

“…As is well known, PZT (Pb(Zr x Ti 1-x )O 3 ) as a ferroelectric system can be improved by changing the composition in order to make it suitable for technological applications, such as piezoelectric transducers, pyroelectric detectors, and nonvolatile ferroelectric memories [1][2][3] . In the same way, multiferroic materials, in which electric and magnetic orderings coexist in a single phase, have attracted the attention of the scientific community 4,5 .…”

Micro Piezoelectric Ultrasonic Motors

“…We developed new ceramic series based on PZT-Pb(Mn,X)O 3 (X = Sb, Nb) systems, which can be used for 10 times higher input/output power range than the commercially available Hard PZT's without generating significant heat. Refer to some recent papers [8,9] on this issue.…”

Strain Mechanisms in Lead-Free Ferroelectrics for Actuators

“…The high power, small signal regime entails high frequency applications with a certain degree of non-linearity due to the relatively large electric field input above 0.006 kV/mm applied during service. 8,9 This work will mostly concern the characterization of piezoceramics in the low power, small signal regime and large signal regime, as pointed out in Actuators used in fuel injectors work in the most demanding conditions. 10 Table 1.1 summarizes service requirements of piezoelectrics in fuel injectors.…”
