The magnetic properties of epitaxially grown Fe/NiO/Fe(001) trilayers have been investigated, for different thickness of the NiO spacer, by means of Magneto-Optical Kerr Effect. It was found that the NiO thickness tAFM has a critical value tC for the magnetic copuling between the Fe layers: for tAFM < tC the magnetization directions align perpendicularly in zero applied field, while the alignment is collinear for thicker spacers. A phenomenological model has been developed to reproduce and discuss the results.

Abstract
The magnetic properties of epitaxially grown Fe/NiO/Fe(001) trilayers have been investigated, for different thickness of the NiO spacer, by means of Magneto-Optical Kerr Effect. It was found that the NiO thickness tAFM has a critical value tC for the magnetic copuling between the Fe layers: for tAFM < tC the magnetization directions align perpendicularly in zero applied field, while the alignment is collinear for thicker spacers. A phenomenological model has been developed to reproduce and discuss the results.File in questo prodotto:
