Abstract

Crystal structure of ferroelectric silver niobate AgNbO³ was determined (Pmc2¹) by convergent beam electron, electron, neutron, and synchrotron diffraction techniques and first-principles calculations. The atomic displacements along the c axis in Pmc2¹ AgNbO³ are responsible for the spontaneous polarization, ferroelectricity, and the paraelectric-ferroelectric phase transition.
