Iron/Silver (Fe/Ag) Thin films are prepared by molecular beam epitaxial technical on to kinds of substrate: Magnesium dioxide(Periclase) single crystalline substrates (MgO (001)) and Silicon polycristalline one (Si (100)/SiO2). The magnetic layer thickness is fixed at 300Å and the buffer layer Ag films thickness is varied from 0Å to 150Å by a step of 50Å. We are used two kinds of substrates, to find the effect of the variation in the kind of substrate on the magnetic properties such as the coercive field (Hc) of these thin films. The magnetic properties of these films are characterized by the Magneto optical Kerr effect (MOKE) technical at room temperature with a static magnetic field applied parallel to <100> and <110> Fe film directions. The analysis of the hysteresis loops who registered by MOKE indicates the presence of an in plane easy magnetization axis in the two kinds of samples and shows a dependence of the uniaxiale anisotropy on the Ag buffer layer thickness in the case of sample how’s deposited into Mgo single crystalline substrates, and it appear in the large values of coercive fields in the case of <100> applied field direction, which also depend with the variation of the Ag buffer layer thickness.
