摘要：

A sharp kink in the temperature dependence of the electronic spin-lattice relaxation rate near 200 K was found in the high-temperature superconductors YBa2Cu4O8 and YBa2Cu3O6+x. The effect is correlated with opening of a spin gap and microscopic phase separation. (C) 1999 American Institute of Physics. [S0021-3640(99)00808-7].
