Magnetic anisotropy was investigated by magnetic torque measurements for the layered High-Tc superconductors La-substituted Bi2Sr2CuO6+δ (Bi-2201) (Tc=28 K), zinc-phthalocyanine (ZnPc)-intercalated Bi2Sr2CaCu2O8+δ (Bi-2212) (Tc=55 K) and oxygen controlled Bi-2212 (Tc=57 approx. 86 K). Magnetic anisotropy is much affected by the interlayer coupling. The boundary of the crossover from three dimensional vortex lines to two dimensional vortex pancakes shifts toward higher field with increasing the interlayer coupling. The irreversible region in H-T phase diagram becomes small by decreasing the interlayer coupling.
