Effects of ion‐beam bombardment and post‐annealing on the structural and magnetic properties of Fe/Pt multilayers

“…Different methods such as high energy ion bombardment [3], adding a nonmagnetic element [4], and annealing [5] have been employed to alter and improve the magnetic properties for magnetic media applications. In this paper, moderate ion-beam bombardment and post annealing was used to investigate the phase evolution of Fe/Pt multilayers, and correlate it with the magnetic properties.…”

Microstructural characterization of L1 FePt/MgO nanoparticles with perpendicular anisotropy

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Since most applications for high density media require a proper particle size (Ͻ9 nm in diameter), the size effect of FePt nanoparticles on the phase transformation from the disordered A1 FePt (fcc) to the ordered L1 0 FePt (fct) structure becomes an important issue. 4 Studies have shown that there is a strong size effect on the ordering of FePt nanoparticles, and that small fcc FePt nanoparticles need much longer time to complete ordering upon isothermal annealing.…”

Additive Effects of AlN and MgO on FePt Nanoparticle Assembly

“…Numerous studies on FePt granular films have been conducted so far. [5][6][7] However, most of the films reported so far were with random crystal orientation and too thick, obviously inappropriate for magnetic recording.…”
