Abstract

Several series of Nb/Gd/Nb triple layers have been grown in UHV by e--beam evaporation onto sapphire (1120BAR) substrates at 300 K. The superconducting transitions have been measured resistively and by dc-susceptibility, the ferromagnetic transition with the transverse magnetooptical Kerr effect. The Gd layers show long-range ferromagnetic order only above a layer thickness of 20 angstrom, which ...
