The superconducting properties of spin-glass superconducting multilayers made of Nb (superconducting) and CuMn (spin glass) have been studied. The superconducting critical temperature Tc of the multilayers was strongly dependent on the thickness of the spin-glass layers. The Radovic et al. theory [Phys. Rev. B 44, 759 (1991)], which foresees a phase difference 0≤φ≤π between neighboring superconducting layers, has given a qualitative description of these experimental data. The parallel and perpendicular critical magnetic-field measurements have shown many interesting effects related to the reduced dimensionality of the samples.
