Averback, R.S. Krasnochtchekov, Pavel Georgievitch 2015-09-25T20:52:50Z 2015-09-25T20:52:50Z 10000-01-01 2004 2004 Analysis of magnetization data in the framework of superparamagnetic theory revealed that at irradiation temperatures Ti below T i ∼350°C, phase separation in Cu-Co films of all compositions stabilizes at high doses (by 5 x 1015 ions/cm 2), indicating the existence of temperature-dependent steady states for these alloys under irradiation. At temperatures higher than 350°C, macroscopic-like coarsening is observed. At low temperatures (room temperature and below), FC/ZFC (field cooled/zero field cooled) measurements clearly show the randomizing effect of irradiation. The observed phase separation behavior of Cu-Co system under irradiation fits well with the predictions of the theoretical model of Enrique and Bellon for immiscible alloy films under irradiation.
