In order to verify the existence of fourfold ferroelastic domain wall, which is suggested by group-theoretical consideration, polarizing microscopy and X-ray Laue photography experiments were carried out for BiVO4 crystal which is expected to have fourfold walls only. The experimental results showed that the domains in ferroelastic BiVO4 have fourfold rotational symmetry relationship and the domain walls are characterized by these fourfold symmetry elements. This proves the domain walls in BiVO4 to be the fourfold wall and they were indexed as (101) and (101) in monoclinic reference system.
