“…Relaxor ferroelectrics have the advantages of low loss, high energy storage, and large electrostriction, making them used as capacitors, electromechanical transducers, sensors, and other components. [1,2] Pb(Mg 1/3 Nb 2/3 ) 3 (PMN) [3] is a typical relaxor ferroelectric in which B sites of perovskite are occupied by random mixtures of heterovalent cations. Temperature-dependent dielectric constant ε r of relaxor ferroelectric PMN shows strong frequency dispersion before a temperature T m where a broad dielectric maximum occurs, the T m shifts toward high temperature with increasing frequency.…”

Lead-free Ba 0.8 Ca 0.2 TiO 3 -xmol%Ba(Mg 1/3 Nb 2/3 )O 3 (abbreviated as BCT20-xBMN, x ¼ 0-8) ceramics are fabricated by a conventional solid-state reaction method. All BCT20-xBMN ceramics have pure perovskite phases which gradually change from tetragonal phase to cubic phase. The average grain size decreases significantly from %23 to %1.2 μm with the increase in BMN content. The T m corresponding to the dielectric maximum of BCT20-xBMN decreases with the increase in x, and the room temperature dielectric constant increases significantly. The recoverable energy storage density W rec and efficiency η% are enhanced to 0.17 J cm À3 and 81.3% for BCT20-6BMN due to the reduced remanent polarization by BMN doping. The W rec increases with increasing temperature and shows peak values near the T m . The η% of BCT20-6BMN and BCT20-7BMN has good temperature stability due to enhanced relaxor behavior.
