  Magnetic nano-dot arrays with (tilted) perpendicular anisotropy are useful for the high-density magnetic recording. In this study, we deposited two kinds of ferromagnetic sample: Fe55Pd45/Si (100)-plane and Fe55Pd45/Si (100)-pillar. Each sample underwent a rapid thermal annealing (RTA) treatment; with a heating rate of 40oC/sec up to 500oC, being annealed there for 30 minutes, and then quenched to room temperature. After fabrication, X-ray diffraction (XRD) indicated that after RTA the FePd alloy transformed from the fcc to the fct phase with lattice constants: a = 0.380 nm and c = 0.378 nm. The Si(100) pillars are 500 nm in length, 65nm in diameter, and with a density of about 1012 cm-2. On top of each Si(100) pillar there sat a prolate ellipsoid shape Fe55Pd45 particle: length L ≅ 108 nm and short-axis diameter d ≅ 67 to 83 nm. Magnetic domain (MD) pattern of the Fe.. View More»
