Abstract

Positive muon spin-relaxation (µ+SR) measurements on a spin-ladder material Na2Co2(C2O4)3(H2O)2 are reported. We find that the relaxation rate, λ, under a longitudinal field of 3950 Oe increases with decreasing temperature, T, and is a maximum at Tpeak ≃ 18 K. Below Tpeak, λ decreases with decreasin...
