摘要：

Patterned magnetic structures with sizes ranging from 30 nm to 5 mu m have been fabricated to investigate the magnetization reversal of Co/Pd islands with perpendicular anisotropy. The nucleation field for reversal in islands capable of supporting. a multidomain ground state (size ranging from 200 nm to 5 mu m) is higher than the domain wall propagation field and is characterized by a Stoner-Wohifarth-like angle dependence. Pre-reversed nucleation sites in the islands leads to the 1/cos(theta) switching behavior indicative of domain wall motion.
