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. El

Single crystals of antiferromagnetic La2CuO4+ b (TN=250K) which show superconductivity ( Tc=32K ) with the Mcissner fraction of 9.1% were grown from a melt with excess of CuO. The electrical resistivity and the Hall effect have been measured on the as-grown and heat-treated samples under high magnet
Magnetic properties were investigated for single crystals of La 2Àx Ca x CoO 4 ð0:5pxp0:8Þ and for polycrystalline samples of La 2Àx Ba x CoO 4 ð0:5pxp0:9Þ. In the Ca system, the effective moment m eff decreased with increasing x from 4.0 m B ðx ¼ 0:5Þ to 3.0 m B ðx ¼ 0:720:8Þ, accompanied by a stee
