✦ Synopsis

Single crystals of La2_,Ba,Cu0, with 5 mm diameter and 25 mm length have been grown by the traveling solvent floating zone (TSFZ) method. The composition of the single crystal containing maximum Ba content and showing a superconducting transition at 30 K was determined to be La ,.935Ba0.065Cu04. Electrical resistivities along the c-axis and in the ab-plane reveal significant anisotropy. Magnetic susceptibilities have been measured under a field of 50 Oe from 5 to 50 K. Under fields Hlab-plane and HIlab-plane, the single crystal demonstrates 3.6% and 0.7% Meissner fractions, respectively, at 5 K.
