摘要：

Additive effects of C, SiO2, and Al2O3 on L1(0)- FePt epitaxial thin film were studied. Samples were fabricated by co- sputtering of FePt and ( C, SiO2, and Al2O3) on MgO ( 1 0 0) substrate at 973 K. These additives effectively reduce the particle size of FePt. C additive deteriorates the crystal orientation, while Al2O3 additive gradually degrades the L1(0) ordering. On the other hand, SiO2 additive can reduce the particle size while keeping the high c- axis orientation and higher degree of L10 ordering. (c) 2006 Elsevier B. V. All rights reserved.
