Özet

Magnetic coercivity and anisotropy have been investigated in amorphous Co50Fe50 t/Tb t multilayers with perpendicular anisotropy. The thin CoFe layer does not crystallize when sandwiched between Tb layers. The saturation magnetization M-s (similar to 10(6) A/m) and perpendicular magnetic anisotropy constant K-u (similar to 10(5) J/m(3)) combined with low coercivity mu H-0(c) (10-10(2) mT) have been obtained. These magnetic properties can be tuned. These amorphous multilayers could be designed to suit specific spintronic applications. (C) 2012 Elsevier B.V. All rights reserved.
