Ferromagnetism of Dy films containing embedded Fe atoms and nanoparticles

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 introduced either as Fe atoms from a conventional MBE source or as 1.8 nm diameter Fe nanoparticles fr...
