Influence of Annealing Conditions on Structure and Magnetic Properties of Nanodimensional Fe50Pt50(15 nm)/ Ag(30 nm)/Fe50Pt50(15 nm)/SiO2(100 nm)/Si(001) Film Composition

We study the influence of 30-nm-thick Ag intermediate layer and annealing duration in a vacuum at the temperature of 600 °С on formation of chemically ordered L10(FePt) phase in nanodimensional film composition (NFC) of Fe50Pt50(15 nm)/Ag(30 nm) /Fe50Pt50(15 nm) on planar SiO2(100 nm)/Si(001) substrate.

Influence of Annealing Temperature on Structure and Magnetic Properties of Nanodimensional Fe50Pt50(15 нм)/ Ag(30 нм)/Fe50Pt50(15 нм)/SiO2(100 нм)/Si(001) Film Composition

We study the influence of annealing temperature in range of 300–900 °С and intermediate Ag layer on processes of diffusional phase formation and transition of chemically disordered magnetic-soft А1(FePt)FCC phase to chemically ordered magnetic-hard L10(FePt)FCT phase in nanodimensional Fe50Pt50(15 nm)/Ag(30 nm)/Fe50Pt50(15 nm) film composition (NFC) on SiO2(100 nm)/Si(001) substrate. We investigate its structure, morphology and magnetic properties. We show that after deposition in NFC under study the phase А1(FePt)FCC is observed.

The Influence of Annealing Conditions on Structure and Magnetic Properties of Nanodimensional Fe50Pt50 Film on Planar SiO2(100 nm)/Si(100) Substrates

It is studied the influence of annealing conditions in temperature range of 300– 900 °С on formation of magnetic-ordered L10(FePt) phase in nanodimensional Fe50Pt50(15 nm) /Ag(3 nm)/Fe50Pt50(15 nm) film composition (NFC) on planar SiO2(100 nm)/Si(100) substrate. It is investigated its structure, morphology and magnetic properties. It is shown that the formation of L10(FePt) phase occurs at annealing 700 °С for 30 s and heating rate of 5 °С/s. Amount of L10(FePt) phase increases with increase of annealing temperature.

In this paper, we study the influence of 3-nm-thick Ag intermediate layer and annealing duration in a vacuum at the temperature of 600°С on formation of chemically ordered L10(FePt) phase in the nanodimensional film composition (NFC) of Fe50Pt50(15 nm)/Ag(3 нм)/ Fe50Pt50(15 nm) on the planar SiO2(100 нм)/Si(100). substrate. Its structure and magnetic properties are investigated. We show that the formation of L10(FePt) phase takes place during annealing whose duration is 30 мин. min.
