Temperature dependence of the velocity Vs and the attenuation of the ultrasonic waves are measured to investigate the relation between the spin type of magnetic order and lattice instability of the low-temperature tetragonal phase in La2-xSrxCuO4 (x ∼ 1/8). In the field above 8 T along the [0 1 0]o direction of the orthorhombic notation, a significant increase of Vs in the c44 mode is observed below ∼15 K where spin-flop occurs. This gigantic increase of Vs suggests that the structural transformation from the orthorhombic to the low-temperature tetragonal phase is induced by the spin-flop.
