Hysteresis loops measured from polar MOKE for three samples deposited at different Ar pressures.
The coercivity and the full width half maximum, , of (Co/Pd) multilayers as a function of the deposition argon pressure.
Normalized magnetization vs normalized applied field to the coercivity for nonpatterned samples deposited at different argon pressures. The larger the deposition pressure the narrow the switching field is.
MFM images of taken at remanence states after removing the applied field indicated on each figure. The top series of images are for the sample deposited at 1.5 mTorr with of 5.1°. The bottom series of images are for the sample deposited at 5 mTorr deposition pressure and having of 3.8°.
Switching probability as a function of applied field for samples deposited at 1.5, 3, and 5 mTorr. No major difference in switching probability for samples deposited at 3 and 5 mTorr but 50% of the number of dots switched at larger field compared to the sample deposited at low pressure of 1.5 mTorr.
SFD for the three samples shown in Fig. 6. The applied field is normalized to their respective coercivities.
