Abstract

The magnetic behavior of MnZnTi and NiZn ferrite films, deposited by laser ablation, is studied comparatively to that of the bulk material, using a vibrating-sample magnetometer (VSM), transmission, and conversion electron Mossbauer measurements. Both the VSM and Mossbauer analysis show that the films exhibit the single phase pattern of the target material. Mossbauer hyperfine field values for films are close to those found for the bulk, and this accounts for the same saturation magnetization values determined by VSM. Laser ablated films exhibit a higher coercive field, which is explained in terms of the crystallite size distribution, with average values of 300-600 nm, as estimated from the Mossbauer line broadening.
