抄録

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.
