The First Room‐Temperature Ferroelectric Sn Insulator and Its Polarization Switching Kinetics

Sr3Sn2O7 is the first room‐temperature ferroelectric Sn insulator with switchable electric polarization. The ferroelastic twin domains are observed using a polarized optical microscope. The polarization hysteresis loop clearly demonstrates the ferroelectric property. Intriguing polarization switchin...

Beschreibung
Zusammenfassung:Sr3Sn2O7 is the first room‐temperature ferroelectric Sn insulator with switchable electric polarization. The ferroelastic twin domains are observed using a polarized optical microscope. The polarization hysteresis loop clearly demonstrates the ferroelectric property. Intriguing polarization switching kinetics are observed through an in situ poling process using a dark‐field transmission electron microscopy technique.
