Abstract We analyze the spin relaxation time 1/T1 for a system made of weakly coupled one-dimensional ladders. This system allows us to probe the dimensional crossover between a Luttinger liquid and a Bose-Einstein condensate of magnons. We obtain the temperature dependence of 1/T1 in the various dimensional regimes, and discuss the experimental consequences.
