دراسة اللا تناحي و الدورية في توزعات للمغنطة بمجهرية القوة المغنطيسية

الملخص EN

Magnetic force microscopy (MFM) is a variety of atomic force microscopy, where a sharp magnetized tip scans a magnetic sample; the tip-sample magnetic interactions are detected and used to reconstruct the magnetic structure of the sample surface.

In this work, we have used Dynamic (AC) noncontact AFM (NC-AFM) mode.

A mode which provide micrographs for topography, oscillation amplitude changes and phase shift.

Using the autocorrelation Operator, we studied the anisotropy and periodicity in magnetization distributions in different generations of floppy disks.
