| Title: | Observation of Two Different Oscillation Periods in the Exchange Coupling of Fe/Cr/Fe(100) |
| Published: | January 01, 1991 |
| Abstract: | Oscillations of ferromagnetic to antiferromagnetic exchange coupling between two Fe layers separated by a Cr spacer of linearly increasing thickness were investigated by imaging the magnetic domains with scanning electron microscopy with polarization analysis. Up to six oscillations in the coupling with a period of 10-12 Cr layers were observed, and, in the case of an extremely well ordered Cr interlayer, additional oscillations with a period of 2 Cr layers were observed. |
