17O NMR Study of Charge Ordered La1.885Sr0.115CuO4

We successfully isolated the 17O NMR signals at the planar sites in La1.885Sr0.115CuO4 (Tc = 30 K) by applying an external magnetic field along the a-axis of a single crystal. We demonstrate that charge order enhances incommensurate Cu spin fluctuations below \(T_{\text{charge}} \simeq 80\) K.
