In-situ neutron diffraction study of Pb(In₁/₂Nb₁/₂)O₃-Pb(Mg⅓Nb⅔)O₃-PbTiO₃ single crystals under uniaxial mechanical stress
In this paper, we report the phase transition behavior of ternary relaxor ferroelectric single crystals of 0.25Pb(In1/2Nb1/2)O₃-0.44Pb(Mg1/3Nb2/3)O₃-0.31PbTiO₃ subject to a uniaxial mechanical stress up to 400 MPa. The resultant in situneutron diffraction data are interpreted in terms of the polarization rotation theory and provide direct structural evidence for the stress-induced polarization rotation pathway deduced from studies of macroscopic physical properties under stress. It is suggested...[Show more]
