Structure and magnetism of MBE-grown Co/Cu multilayers

Structural and magnetic properties of Co/Cu multilayers deposited in the ultra-high vacuum molecular beam epitaxy system on glass substrates with different modulation periods were investigated. A structural characterization was performed by means of RHEED and Auger spectroscopy (in situ) small angle X-ray reflectivity and scanning tunneling microscopy. The samples obtained have a textured, polycrystalline layered structure for deposition at room temperature. Magnetization and in-plane magnetoresistance measurements were performed as a function of Cu and Co layer thickness. An influence of different buffers and of interface quality on magnetic properties was investigated (author)
