Silver nuclei form an antiferromagnetic spin system in which the conduction-electron-mediated indirect Ruderman-Kittel exchange interaction dominates over the nuclear dipolar forces. We have studied magnetic ordering by measuring the dynamic susceptibility of polycrystalline silver foils down to about 0.5 nK (S > 0.4 R In2) using SQUID-NMR techniques. We obtain Tc=(560±60) pK for the transition temperature at B = 0 and Bc = 100 μT for the critical field extrapolated to T = 0.
