N2 - The nuclear spin-lattice relaxation time T1 of 31P nuclei in the title compound is measured for the first time and interpreted in terms of a modified spin-wave theory. We establish a novel scenario for one-dimensional ferrimagnetic spin dynamics - it is three-magnon processes enhanced by exchange scattering, rather than Raman processes, that make the major contribution to 1/T1.
