Paper Abstract

Ferromagnetic resonance (FMR) absorptions from six fine particle-samples of barium ferrite were studied over a temperature range of -195 degree(s)C to 500 degree(s)C. It was found that the shape of the FMR absorption signal is affected by the particle shape and crystalline anisotropy of each sample. From this analysis, the first magnetic anisotropy constant K1 was estimated approximately as a function of temperature. The estimation suggested that the value of K1 was sensitive to the condition of preparation of fine powders. In addition the photosensitivity of the LiNbO3:BaFe doped crystal was enhanced, suggesting the importance of Barium Ferrite powder as a potential candidate with NOL materials.
