摘要：

We have studied the magnetic behaviour of polycrystalline dysprosium films grown in their pure state and containing Fe impurity. The films were grown by MBE in ultra-high vacuum and Fe impurity was We attribute the low moment in the Dy films containing nanoparticles to alloying within the particles producing a significant proportion of high-Fe-concentration Dy-Fe alloy.
