Abstract:SUMMARY
Microwave‐assisted magnetization switching (MAS) has been expected as one of the prominent future ultra‐high‐density magnetic recording technologies. In this paper, we have studied the radio frequency (RF) field dependence of the switching behavior of Co/Pt nanodot arrays with various dot diameters. While the critical frequency increases and the minimum switching field decreases with increasing the RF field, MAS behavior critically depends on the dot size. For small dots less than 130 nm in diameter, t… Show more
