Description

Zero field muon spin relaxation measurements of the ceramic high-Tc superconductors HoBa2Cu3O7-δ, (Tc≅93K) and ErBa2Cu3O7-δ (Tc≅95 K) reveal the sharp difference between the behaviours of the muon spin relaxation rate at temperatures below 20 K. This fact may be explained by assumption that the frequency of fluctuations of Er magnetic moments exceeds by far the fluctuation frequency of Ho in 1-2-3 compounds. (orig.)
