Abstract

The sound velocity V_s of La_2-xSr_xCuO ₄ around x = 0.220 has been measured in magnetic fields up to 12 T. The increase of V_s by applying magnetic fields was observed in case of x = 0.220, and resembles the enhancement of the increase of V_s observed in the concentration of x around 0.115. The magnetic field dependence of V_s in x = 0.220 scales with that observed in x = 0.120. This result strongly suggests that the observed magnetic field effect on the sound velocity has the same origin with that in x ∼ 0.115.
