Abstract
Two-dimensional arrays of amorphous Gd-Co square particles with thickn ess around 200 nm were fabricated on 20 nm thick Nb films by means of high-resolution e-beam lithography and sputter deposition. Interesting oscillations due to the fluxoid quantization were observed in the mag netoresistance measured around the superconducting transition temperat ure of Nb films. The superconducting state of the Nb films seems to be modulated by stray fields produced by the square magnetic particles.
