Emergent polar order from interlayer microstrain in layered perovskites

Ferroelectric materials with switchable polarization and nonlinear dielectric responses are promising candidates for reconfigurable communication systems. However, their practical use is limited by an inherent trade-off: large dielectric tunability is usually accompanied by high dielectric permittivity and increased lo...

Large strain and high reversible dielectric tunability in Sm-modified PMN-PT ceramics

Relaxor ferroelectrics offer dynamic polar responses desirable for adaptive electronics, yet they are fundamentally constrained by a long-standing trade-off: compositions that deliver large electric-field induced strain typically suffer from pronounced hysteresis, while highly tunable ferroelectrics exhibit limited...
