Fe thin films have been deposited by thermal evaporation onto glass substrate. The thickness ranges from 76 to 431 nm range, while deposition rates are between 0.3 and 13.4 Å/s. The magnetic properties of these Fe thin films are investigated. The magnetic properties were inferred from B-H hysteresis curves. The magnetic field was applied both in-plane and perpendicular to the film. The coercive field HC and the saturation field HS were derived for both configurations. The effects of the preparation conditions – thickness, deposition time and deposition rate – on the HC and HS behaviors are investigated. Interesting features are observed as a function of the elaboration conditions. Also, the variation of HC with grain size reveals the different mechanisms responsible for the coercive field values.
