Abstract: A systematic investigation of magnetic switching behavior of CoCrPt based capped media is performed by varying the thickness of the capped layer. We find out that in the CoCrPt/SiO2TiO2Ta2O5 granular layer, CoCrPt magnetic grains are separated by nonmagnetic oxide grain boundaries. The amorphous grain boundary phase in the granular layer propagates to the top surface of the capped layer. It shows that a thicker capped layer effectively reduces macroscopic switching field distribution. Both strong exchange interactions and narrow intrinsic switching field distribution make contribution to the reduction of macroscopic switching field distribution. © 2012 DSI.
