EXPERIMENTAL AND THEORETICAL DOMAIN PERIODS IN BaCo_xTi_yFe_12-x-yO₁₉

Abstract

  Domain sizes in demagnetized samples are reported for polycrystalline films of thickness down to 30 nm and for thin single crystal weges of pure and Co/Ti doped BaM hexaferrites. The results compare well with domain theory which is amended by taking into account results of micromagnetic computations.
