This paper is a report on the results of a study done on the superconductive transitions of Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub [ital y]]/Bi[sub 2]Sr[sub 2]CuO[sub [ital x]] (BSCCO/BSCO) multilayer thin films in magnetic fields parallel or perpendicular to the films, which were prepared using a multitarget rf magnetron sputtering technique. In the multilayers with BSCCO (a superconductor) of constant nominal layer thickness of 47 A, the resistive transition showed broadening and reduction of [ital T][sub [ital c]] with an increase of the BSCO (a nonsuperconductor) layer thickness from 36 A to 144 A. The resistive transition showed a slight broadening, even under the aligned magnetic field parallel to the Cu-O planes. This result suggests that the superconductive layers are coupled through BSCO layers, and that the interlayer coupling was induced by the proximity effect.
