Abstract :
In this paper, the Curie temperature was assumed to only depend on the quantity of deposited material. We have shown that in the particular case of thin Fe films grown on Ir(001) by MBE, two magnetic transitions are observed in a thin Fe film with a fractional number of deposited monolayers (ml). The Curie temperatures (T/sub c/) were determined by both Mossbauer spectroscopy and ac susceptometry.
