title: The First Room-Temperature Ferroelectric Sn Insulator and Its Polarization Switching Kinetics.
abstract: Sr3Sn2O7is 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.
