Introduction of VN underlayer and caplayer for preparation of Mn₄N(001) single-crystal thin film with perpendicular magnetic anisotropy

Barium and Strontium Ferrite Perpendicular Thin Film Media with a Sendust Soft Magnetic Underlayer

The possibility of using sendust (FeAlSi) as the soft magnetic underlayer for hexagonal barium ferrite (BaM) and strontium ferrite (SrM) was studied. Sendust films were found to retain their soft magnetic properties with a rapid thermal anneal (RTA) at 800 C for 60 s, which is necessary to crystallize the as-deposited amorphous BaM and SrM films. Several film structures with sendust films as th...

A TEM Structural Study of the Origin of Perpendicular Magnetic Anisotropy in Ultra-thin CoFeB Film

Perpendicular magnetic anisotropy (PMA) at ferro-magnetic transition metal/insulator interfaces has attracted intensive interest in the context of developing various spintronic devices. Magnetized out-ofplane magnetic tunnel junctions (p-MTJ) are now developed for spin transfer torque (STT) magnetic random access memories (STT-MRAM) applications where the strong perpendicular anisotropy origina...

Nanostructured FePt:B2O3 thin films with perpendicular magnetic anisotropy

Switching of magnetic easy-axis using crystal orientation for large perpendicular coercivity in CoFe2O4 thin film

Perpendicular magnetization and precise control over the magnetic easy axis in magnetic thin film is necessary for a variety of applications, particularly in magnetic recording media. A strong (111) orientation is successfully achieved in the CoFe2O4 (CFO) thin film at relatively low substrate temperature of 100 °C, whereas the (311)-preferred randomly oriented CFO is prepared at room temperatu...

Edge-modulated perpendicular magnetic anisotropy in [Co/Pd]n and L10- FePt thin film wires

Thickness modulation at the edges of nanostructured magnetic thin films is shown to have important effects on their perpendicular magnetic anisotropy. Thin film wires with tapered edges were made from [Co/Pd]20 multilayers or L10-FePt films using liftoff with a double-layer resist. The effect of edge taper on the reversal process was studied using magnetic force microscopy (MFM) and micromagnet...
