Abstract:
The Al 2 O 3 -FePd 3 structure was fabricated by aluminothermy, or the Goldschmidt reaction. The initial structure was prepared by the formation of a highly-ordered L 1 0 -FePd epitaxial film with the use of the solid-state reaction in a Fe(001)/Pd(001) bilayer system on the MgO substrate. To obtain a granular structure, the L 1 0 -FePd samples were oxidized in air with the subsequent deposition of an aluminum layer onto their surface and vacuum annealing. Depending on annealing time and temperature, a system of L 1 2 -FePd 3 grains 5 nm in size was formed in an Al 2 O 3 insulating matrix. Parameters of thermal treatment of the initial structure are presented, the occurring phase transformations are described, and the magnetic characteristics are measured. It is established that the ordered L 1 0 -FePd phase is obtained at an initiation temperature of the reaction of about 450 о С and the granular L 1 2 -FePd 3 system forms at 600-650 °С.
