摘要
The spin-lattice and spin-spin relaxation times have been measured for Cu-63,Cu-65 NMR in the infinite-layer antiferromagnet SrCuO2 in the ordered state for temperatures from 4.2 to 361 K. In the region of low temperatures (T less than or equal to 250 K), both relaxation processes are of the same nature and the main contribution to the relaxation rate is associated with the diffusion of a small number of holes with an activation energy of similar to42 meV. In the high-temperature range (T > 250 K), contributions to the transverse relaxation rate exhibit redistribution and this relaxation process is determined predominantly by indirect interactions.
