摘要: Multilayers consisting of thin Fe and Cr layers were prepared on MgO(100) glass substrates by alternate deposition in ultrahigh vacuum. It is confirmed that the giant magnetoresistive change found Baibich et al. Fe/Cr multilayers GaAs(100) reproduced both types samples. The resistivity Fe(27 A)/Cr(12 A) multilayer MgO reduced 37% applying 7 kOe at 77 K 13% 300 K. A sample a substrate also shows 27% with
