Magnetic studies of Fe-Y compositionally modulated thin films

Compositionally modulated thin films of Y/Fe have been studied by using SQUID magnetometry. Samples were grown by electron‐beam evaporation onto Kapton substrates. In the low applied field regime, the samples show irreversible behavior when they are submitted to ZFC‐FC magnetization processes, incre...
