  We used temperature-dependent neutron diffraction measurements on FeVO4 to
understand the temperature driven anisotropy and observed that the maximum
change for a and b lattice parameters in conjunction with a large contraction
in angle \beta\ as a function of temperature. The least changes are observed
for the c lattice parameter and in \gamma\ angle. From these structural
parameters, it can be said that, FeVO4 exhibits large structural anisotropy
with lowering temperature. The large change in lattice parameters in magnetic
phases i.e. below 22 K explains the strong magnetostructural coupling in FeVO4.
