摘要: 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 300A the buffer Ag varied from 0A 150A a step 50A. We used two substrates, find effect variation in kind substrate properties such as coercive field (Hc) these thin films. characterized Magneto optical Kerr (MOKE) room temperature with static applied parallel Fe film directions. analysis hysteresis loops who registered MOKE indicates presence an plane easy magnetization axis samples shows dependence uniaxiale anisotropy case sample how’s deposited into Mgo it appear large values fields direction, which also depend thickness.
