Description

Angular magnetic field dependence of the critical currents of (Bi2 Sr2CaCu 2O8)m/(Bi 2Sr2CuO6)n multilayers has been investigated, m and n being the numbers of 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 Jc(H) is independent of a magnetic field H≤20T parallel to the layers. We demonstrate that this system behaves like an ideal 2D superconductor. copyright 1997 The American Physical Society
