摘要：

In the present work, NiFe2O4 (NFO) and MgFe2O4 (MFO) thin films are deposited on MgAl2O4 (MAO)(1 0 0) substrate using pulsed laser deposition technique to investigate the atomic replacement effects on the magnetic anisotropy of the films. X-ray diffraction analysis confirms the c-oriented growth of the films. Magnetic field dependent magnetization discloses the soft magnetic nature, lower saturation magnetic field and large magnetic anisotropy in MFO(25 and 50 nm) films as compared to NFO(27 and 47 nm). In particular, MFO(50 nm) film exhibits a symmetrical ferromagnetic resonance spectrum in contrast to the bulk counterpart. The angular dependence of the resonance field reveals the uniaxial magnetic anisotropy in MFO(50 nm) film, making it one of the potential candidates for energy-efficient information and communication based spintronic devices. An induced magnetic anisotropy in MFO may be ascribed to the magneto-elastic Ni-2(+) ions replacement with non-magneto-elastic Mg2+ ions.
