Abstract

Electrical resistivity has been measured under magnetic fields parallel to the CuO2 planes in LSCO single crystals, where Josephson vortices form in the region between the CuO2 planes. In the crystals over the wide Sr content from the under-doped to the over-doped the vortex glass melting transition is observed in the field range of 1-17.5 T. The glass transition curves strongly depend on the anisotropy of the system, that is, it is suppressed to the low field in the under-doped crystal with large anisotropic parameter. The Josephson vortex glass transition is discussed in terms of the anisotropic parameter.
