Mossbauer spectra of K<sub>2</sub>FeF<sub>5</sub> near the spin-flop phase transition indicate that domains of antiferromagnetic and spin-flopped spins coexist over a range of applied fields Delta B<sub>qpp</sub>=0.4T centred at B<sub>sf</sub>=3.65T. This is discussed with reference to the first-order character of the spin-flop transition.
