Abstract
57Fe Mössbauer spectroscopy has been used to study the noncolinear spiral antiferromagnetic coupling in FeOCl. The paramagnetic to antiferromagnetic transition occurs at 85±1 K. Our Mössbauer studies confirm that the preferential orientations of the spin of Fe3+ which are crystallographically of equivalent sites are parallel to the b and c axes with varied timescale of spin–spin relaxation as a result of competition among the intralayer antiferromagnetic superexchange coupling, ferromagnetic direct exchange coupling, and mixed interlayer dipolar–dipolar interaction.
