【 摘 要 】

The stress anisotropy in epitaxial hard ferrites thin films (BaFe12O19, CoFe2O4) has been investigated using two methods. (a) The thickness dependence of torque curves and magnetic hysteresis loops. (b) The comparison between magnetic and magneto-optic Kerr hysteresis loops. Both analyses confirm the domination of stress in CoFe2O4 whereas in BaFe12O19 films the stress is too weak to compete with magnetocrystalline anisotropy. (c) 2004 Elsevier B.V. All rights reserved.
