摘要：
We analyze the electron paramagnetic resonance linewidth in Rb2Pr(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 1/T-2 has a dipolar origin in contrast to the spin-phonon origin observed in K2Pt(CN)(4)Br-0.3.H2O. This difference could arise from different anisotropy ratios of the transfer integrals. The influence of the interchain coupling is also discussed.
