Gf. Dionne et al., MAGNETIC AND STRESS CHARACTERIZATION OF NICKEL FERRITE CERAMIC FILMS GROWN BY JET VAPOR-DEPOSITION, IEEE transactions on magnetics, 31(6), 1995, pp. 3853-3855
Measurements of magnetization and magnetic anisotropy have been carrie
d out with polycrystalline ferrite films of micron-range thicknesses.
An important feature of the technique used is its capability of determ
ining magnetization without specific knowledge of sample volume, which
can be difficult to measure accurately in situations of nonuniform th
ickness. From these results, noncrystallinity and stress effects assoc
iated with rapid deposition of nickel ferrite films are better underst
ood.
