James made ferroelectrics sample (Bi, La)4Ti3O12 which has a crystal structure like Figure. Basically it was a material of the chemical composition of a Bi4Ti3O12, but it has been made by partly substituting La for Bi. He decide to do some analysis:
1. To confirm whether composition is right or not, what kind of method should he use? (He wants to analyze without destruction of samples. Ferroelectrcs (Bi,La)4Ti3O12 is an insulator.
2. There are a total of 6 oxygens which composes octahedron around the Ti. As a result, of what is known in physics, when coupled with La, Ti's chemical bonding of oxygen is getting stronger. How can we confirm this? (Which method is needed?)
