摘要：

Neutron scattering experiments have been performed to study the dynamic spin properties of single-crystal La1.86Sr0.14Cu0.988 Zn0.012O4 (T(C)= 16 K). The width of S (Q, omega) in momentum space decreases at low omega and at low temperatures. The intensity at low energies at the incommensurate peak position (pi(1-delta), pi)) shows a broad maximum as a function of temperature around the superconducting transition temperature T(C). This behavior is qualitatively similar to that observed by Thurston et al. in La1.85, Sr0.15 CuO4 (T(C) = 33 K).
