Angular magnetic field dependence of the critical currents of (Bi{sub 2} Sr{sub 2}CaCu {sub 2}O{sub 8}){sub m}/(Bi {sub 2}Sr{sub 2}CuO{sub 6}){sub n} multilayers has been investigated, {ital m} and {ital n} being the numbers of {ital c}-axis half unit cells of each phase in one layer. In the limiting case of 15 {Angstrom} thick 2212 layers and 24 {Angstrom} thick 2201 layers per multilayer unit m=1,n=2, we have achieved a superconducting system where J{sub c}(H) is independent of a magnetic field H{le}20T parallel to the layers. We demonstrate that this system behaves like an ideal 2D superconductor. {copyright} {ital 1997} {ital The American Physical Society}
