Towards an understanding of microstructure of patterned FePt dots by magnetometry using pulse fields
Publikováno v:
Journal of Magnetism and Magnetic Materials. 349:5-8
FePt nanodot arrays are patterned and investigated by X-ray magnetic circular dichroism measurements and magneto-optic Kerr effect magnetometry combined with pulse magnetic fields. The experimental results on varied timescale of the applied field are

FePt dot arrays with dot size down to 15 nm are fabricated by film annealing and patterning. The array coercivity shows an increase with dot size decreasing from 100 to 30 nm, and a slight reduction for the 15 nm dot sample. Annealing these dot array

Perpendicular magnetic recording media with a new stacked media structure are proposed in this study. A distinct magnetically isolated granular Co-Pt-TiO2 film and a Co-Pt top layer for controlling an exchange coupling of the granular film were used

A new type of oxide composite film was proposed as perpendicular magnetic recording medium. The storage layer is composed of Co-Pt and Ti-oxide. By transmission electron microscopy (TEM) observation, the film exhibited a well isolated fine granular s

Co-Cr perpendicular magnetic films were sputter-deposited at extraordinarily high Ar gas pressures above 10 Pa at discharge voltages below 300 V. When films were deposited on glass substrates at Ar gas pressures above 10 Pa, they exhibited columnar s
