The direct observation of polarization mixing in nuclear Bragg scattering of synchrotron radiation by 57Fe 2O3 is reported. Application of a magnetic bias field having the appropriate orientation was shown to produce almost complete rotation of the polarized incident beam to a polarized diffracted beam. Rotation of this field about the diffraction vector through 90°caused the diffracted beam polarization to change continuously from through elliptical to as predicted theoretically.
