Magnetic properties of Fe clustering in GaSe epilayers on GaAs(1 1 1)B.

Résumé

Ga1−xFexSe films have been grown on GaAs(1 1 1)B by molecular beam epitaxy. There is no evidence of iron compound formation and Fe aggregate atoms preferentially intercalate in the van der Waals gaps of the GaSe lamellar structure. Field-cooled and zero-field-cooled magnetization have shown an irreversibility and superparamagnetic relaxation with blocking temperatures ranging from 120 to 137 K, consistent with nanoscaled magnetic clusters.
