Abstract

We report ¹³⁹La nuclear magnetic resonance (NMR) measurements on La_2-xSr_xCuO₄ (0.07≤ x ≤ 0.15) and La_2-xBa_xCuO₄ (x=1/8) single crystals, focusing on the spin freezing observed in 1/8-doped lanthanum cuprates. Charge stripe order seems to induce the inhomogeneous slowing down of spin fluctuations toward spin order and compete with superconductivity.
