Phys. Rev. Lett. 63, 1649–1652 (1989)Thermal magnetic relaxation in quasi-two-dimensional Fe filmsSee Also: Erratum Received 1 May 1989; published in the issue dated 9 October 1989 Several Fe(110)/Ag(111) superlattices with the Fe component 2 monolayers thick and the Ag component of varying thickness were produced by molecular-beam epitaxy. The Curie temperature was found to be higher than 500 K and a central feature in the Mössbauer spectra is shown to come from thermal magnetic relaxation of Fe islands. The magnetic hyperfine field has a linear temperature dependence and this is explained by a simple model based on the island structure of the Fe. © 1989 The American Physical Society URL:
