Abstract

The elastic constant of the vortex lattice is measured in order to estimate the superconducting volume fraction of La_1.875Ba_0.065Sr_0.060CuO₄ which undergoes the structural phase transition to the low-temperature orthorhombic (Pccn) phase. The step like change in the elastic constant of c₄₄ mode of the vortex lattice is clearly observed below T_c, and the saturated value of the elastic constant of the vortex lattice is 68% of the theoretical result for the full-Meissner state. This experimental result indicates that, probing with the vortex lattice, the superconducting volume fraction seems to be about two over three under the so-called stripe order in the Pccn phase.
