Abstract

We analyze the electron paramagnetic resonance linewidth in Rb2Pt(CN)4(FHF)0.4 as a function of temperature. Above 60 K, the results are interpreted as a superposition of spin-phonon and spin-spin relaxation effects. The dominant contribution to the relaxation rate l/T2 has a dipolar origin in contrast to the spin-phonon origin observed in K2Pt(CN)4Br0.3 · H2O. This difference could arise from different anisotropy ratios of the transfer integrals. The influence of the interchain coupling is also discussed.
