| Popis: | The structure, magnetic moment and the exchange coupling of epitaxial permalloy(1 1 1)//Ru(0 0 0 1)//permalloy(1 1 1) trilayer were studied by X-ray diffraction and magnetic circular dichroism. An oscillatory anti-ferromagnetic and ferromagnetic coupling as functions of the thickness of Ru layers was verified with an oscillatory period of about 1 nm. An enhancement of orbital moment of Fe in the permalloy layer was observed at the Ru thickness coincident with the anti-ferromagnetic coupling of the permalloy layers. The orbital/spin moment ratio is about 0.4 at Ru thickness of 0.7 nm. |
