a) Calculate the polarization of a BaTi03 crystal (See the following Fig.). The structure transforms from cubic to tetragonal below the Curie point with lattice parameters c and conductivity to 4.06A and 3.97 A respectively. The displacement of titanium ion is opposite to that of oxygen ions. The magnitude of displacement is 0.06 A for titanium, 0.06 A for oxygen ions on the side faces and 0.08 A for oxygen ions on the top and bottom faces of the cube. The displacement of barium ions may be neglected.
