Abstract
The superparamagnetic behavior of ultrathin Fe films at various growth temperatures was studied. The films were grown on an Al₂O₃(0001) substrate by molecular beam epitaxy (MBE). The blocking temperature was strongly dependent on the growth temperature and the 1-nm-thick Fe films were in the superparamagnetic state. The results show that for growth at 673 and 773 K, Fe forms large particles and the magnetic properties are dominated by the individual particles.
