First-principles calculations were performed to compare the relative stability and high-pressure behavior of four different GaAsO4 polymorphs: the ordinary-pressure phase (berlinite, α-quartzlike) and three high-pressure phases: the β -VCrO4-like, the rutile-like and a new hexagonal form, recently discovered and related to rutile.
