摘要：
Mossbauer absorption spectra have been recorded for single-crystal samples of the antiferromagnetic compound (NH4)2FeCl5.H2O in applied magnetic fields up to 10 T. A reorientation of the Fe ion spins from the crystal a axis to the c axis was observed. This transition was found to be a continuous and planar rotation at fields around 2 T. Detailed fitting of the spectra in the spin-reorientation region indicated some inequality between the magnetic hyperfine fields associated with oppositely directed ionic spins.
