Abstract
In Fe(110) films prepared at 300 K on W(110), ferromagnetic long range order is suppressed in a range of coverages between 1.20 and 1.48 pseudomorphic monolayers, whereas below and above this gap of long range order, monolayer and double layer ferromagnetism is observed with Curie temperatures of 230 and roughly 450 K, respectively. Apparently, the frustration of long range order in the gap is caused by indirect interactions of electronic origin between double layer islands, mediated by the surrounding monolayer and its W substrate.Keywords
