Abstract

Bi-O/Sr-Ca-Cu-O multilayered films have been synthesized using two target reactive magnetron sputtering. It is shown that the modulation wavelength \varLambda (c/2 for the crystals) can be simply controlled by varying the deposition time for a one layer unit of Sr-Ca-Cu-O while keeping that for Bi-O constant. The films thus obtained have smooth surfaces and have \varLambda's ranging from 12 to 26 Å, i.e., almost equal to those of the crystalline or intergrowth phases o bserved in the Bi-Sr-Ca-Cu-O system. The thermal stability of these artificially layered films is also reported.
