Giant oscillations of Tc depending on a Cr-thickness were detected. Probable reasons of Tc-oscillation are discussed - periodic cancellation of pair-breacking exchange fields in superconducting V-layer or in fragment Fe/Cr/Fe.PDF, 5 pages, 4 figures, submited in Phys.Rev.LettSuperconductivityMesoscale and Nanoscale Physicstext
