Abstract
It has been shown by annealing simulations of YBa2Cu3O7 epitaxial films tha t the predominant sources of flicker noise in superconducting microstripes in operating ranges of frequency and temperature are related to oxygen tran sitions in the vicinity of boundaries of the small-angle blocks. To make su perconducting microstripes with a dimension of similar to 1 mu m the techni ques of magnetron sputtering, as well as chemical and ion beam etching, wer e applied.
