The influence of quasi‐spin waves on the spin‐lattice relaxation time, T 1 , in ferroelectric K 4 Fe(CN) 6 ·3H 2 O crystals is considered. It is shown that the quasi‐spin waves theory explaines the anomalous behaviour of T 1 near the ferroelectric transition temperature T c . The calculated value of the critical shortening of T 1 at T c and the angular dependences of T 1 near Curie temperature agree well with experimental data.
