An investigation of the low-temperature Faraday rotation spectrum of

Journal of Physics Condensed Matter (1997)

Hugh Masterson J. G. Lunney J. M. D. Coey

The Faraday rotation spectra between 1.5 eV and 2.4 eV are examined for thin films of the hexagonal ferrite , prepared by pulsed laser deposition. Fine spectral detail is observed at 24 K between 1.69 eV and 1.85 eV. A sharp paramagnetic transition at 1.69 eV, with an oscillator strength of , is assigned to the crystal field transition originating on the octahedrally coordinated site. Somewhat weaker diamagnetic transitions above 1.73 eV are tentatively assigned to first-excited-state transitions in the 2b trigonal bipyramidal site. A broader feature with an extremum at 2.23 eV is considered to originate from the transition in tetrahedral sites.

Magnetization Process in Dilute Magnetic Oxides

IEEE Transactions on Magnetics (2010)

J. M. D. Coey Jerome T. Mlack M. Venkatesan Plamen Stamenov

Thin films of dilute magnetic oxides often exhibit high-temperature ferromagnetism with magnetization curves of the form M ¿ M _s tanh (H/H ₀ ); the curves are practically anhysteretic and temperature-independent below room temperature. The absence of temperature-dependent coercivity indicates that the magnetization process is dominated by magnetic dipole interactions, not by magnetocrystalline anisotropy. In a model of ferromagnetic grain boundaries, H ₀ ¿ 0.14M ₀ , where M ₀ is the magnetization of the ferromagnetic regions. Quantitative analysis of more than 200 films of different oxides reveals that only a few percent of the volume of these films is magnetically ordered.
