ABSTRACT
Highly anisotropic Nd[sub 2]Fe[sub 14]B thin film has been produced by triggering crystallization of sputter-deposited amorphous Nd-Fe-B layer by deposition of crystalline Cr overlayer. A downward growth of strongly textured Nd[sub 2]Fe[sub 14]B columnar grains was observed, starting from the interface between the Nd-Fe-B amorphous layer and the Cr overlayer. Cross-sectional transmission electron microscope observation results suggest that the possible mechanism of this peculiar crystallization is the heterogeneous nucleation at the surface of Nd-Fe-B amorphous layer, triggered by the crystalline Cr overlayer. © 2001 American Institute of Physics.

    The magnetization reversal in graded anisotropy Co/Pt multilayers is studied by first order reversal curve (FORC) diagrams. The graded profile influences the nucleation field in thin films. In thicker films (above the threshold value for stripe domain formation), its effect is masked, as the...

    We have studied the magnetic anisotropy of nanometric CoFe2O4 (CFO) thin films grown on (100)SrTiO3 (STO) substrates. It has been found that epitaxial substrate-induced compressive strain makes the normal-to-film axis harder than the in-plane directions. In agreement with some previous reports,...

    Three methods including sol-gel, rf sputtering and pulsed laser deposition (PLD) have been used for the fabrication of high coercivity Co-ferrite thin films with a nanocrystalline structure. The PLD method is demonstrated to be a possible tool to achieve Co-ferrite films with high coercivity and...

    Cu/Ni/Cu films grown epitaxially on Si have shown perpendicular magnetic anisotropy over a wide range of Ni thicknesses.
