Data from the PPMS-AFM

« back

The following data was taken on the PPMS-AFM operated in the Quantum Design PPMS

Bit-patterned media

MFM measurement of the switching field distribution measured at 10 K, in an increasing field from 5500 Oe to 11000 Oe. The dot spacing is 50 nm. Sample courtesy of Dr J. Ahner, Seagate, USA. More...

 

Latest-generation hard disk

After buying a latest-generation commercial hard disk (Seagate Momentus 5400.6), we simply filled it with data and measured in MFM mode. The MFM image exhibits a 14 nm magnetic resolution. More...
