摘要：
We theoretically study the coexistence and mutual influence of magnetism and superconductivity in the ferromagnetic metal/superconductor (FM/S) superlattices (SLs). We found a physically interesting region of the theory parameters, making possible to manage the FM/S SLs superconducting and magnetic properties. We propose the principal scheme of the simplest FM/S/FM/S device which allows one to record information in two separated channels (superconducting and magnetic ones) in a common sample. It is shown that the SLs have more logically different variants of data record than the known FM/S/FM trilayer spin switch. (C) 2002 Elsevier Science B.V. All rights reserved.
