Abstract: A Monte Carlo technique has been developed for simulating the deposition and diffusion of Fe atoms on Al (100) surfaces, and the growth of Fe clusters. The effects of growth conditions on the Fe fractal morphology and the magnetic properties are investigated. The simulated results indicate that with increasing temperature of substrate, the surface morphology evolves from dispersed growth, fractal growth to dense growth, and finally to another dispersed growth. It is also found that the morphology of Fe film greatly affects the magnetic properties, and ramified atomic aggregate with a more compact morphology has a higher Curie temperature.
