Figure 2

(Color online) (a) Sketch of the coherent scattering experiment performed in transmission geometry: the sample is mounted perpendicularly to the incident beam in the near field of a $20\mu \text{m}$ pinhole fabricated by focused ion-beam etching. Speckle patterns are collected with a CCD detector. The CCD image shown here is measured at the Co $L_3$ edge, in ZFC state, at point B of the magnetization loop (Fig. 1). (b) Enlargement of the speckle pattern showing an excellent contrast. (c) RPM cross-correlation pattern obtained from pattern (b). The central peak contains the pure coherent part of the cross-correlated signal from which the degree of magnetic memory is calculated.Reuse & Permissions

Figure 3

(Color online) RPM coefficient $\rho$ (plain dots) as a function of field along the ascending magnetization branch. Each point results from the average of six successive measures. The ascending branch of the SQUID measurement (circles) and scattering intensity (triangles) are plotted together with the memory $\rho$ after normalization for comparison purposes.Reuse & Permissions

Figure 4

(Color online) Schematic of the domain reversal in the F/AF junction, with the AF layer on bottom and F layer on top. Magnetic field is applied perpendicularly. The feature in the AF layer represents the magnetic template imprinted into the uncompensated pinned moments. (a) Nucleation point: domains start to nucleate in the F layer at random locations; (b) further in the reversal, beyond the coercive point, the F domain pattern eventually matches the magnetic topology of the AF template. This configuration is unique.Reuse & Permissions
