Interaction of acoustic waves and ferroelastic domain walls

Abstract
Arrays of domains with 1 mm spacing have been injected into GMO. The injection mechanism is explained in terms of dislocations. Wall motion has been produced by the action of a static shear stress generated by the nonlinear interaction of NPP with an acoustic field. The shear-to-shear reflection coefficient of an “a'’propagating “c'’polarized shear from an “a'’domain wall in NPP was measured to be - 13·7 dB.
