Variation of structure and magnetic properties with thickness of thin Co5gFe26Ni15 films

Variations of phase composition and magnetic properties of electrodeposited nanocrystalline Co-Fe-Ni films with film thickness in the range of 50-500 nm were analyzed. The samples were magnetically soft with coercivity in the range He = 2-20Oe and uniaxial magnetic anisotropy up to Hk = 20Oe. It was...

Description
Summary:Variations of phase composition and magnetic properties of electrodeposited nanocrystalline Co-Fe-Ni films with film thickness in the range of 50-500 nm were analyzed. The samples were magnetically soft with coercivity in the range He = 2-20Oe and uniaxial magnetic anisotropy up to Hk = 20Oe. It was found that Hi decreases and Hk increases with increasing film thickness. The BCC phase dominates at small film thickness up to about 80 nm and the FCC phase increases when the film growths to a larger thickness. The increase of FCC phase correlates with the improvement of the ultrasoft magnetic properties. CO 2004 Elsevier B.V. All rights reserved.
