摘要
We report on muon-spin relaxation/rotation measurements on the Li2CuO2 cuprate. Spontaneous muon-spin precession frequencies are observed below the Neel temperature T-N = 9.2 K. An additional phase transition is observed at T' = 2.4 K, which is interpreted as a spin canting. From the temperature dependences of the internal fields it is suggested that Li2CuO2 consists of two magnetic sublattices, with magnetic moments on both copper and oxygen ions.
