Ni-Co/Cu multilayers have been grown by electrodeposition method from a single electrolyte (based on Ni(SO4).6H2O, Co(SO4).7H2O, Cu(SO4) and H3BO3) using galvanostatic control on titanium sublayers. The X-ray diffraction (XRD) patterns confirmed the multilayered structure with the nanometer thicknesses. Also, electron diffraction x-ray (EDX)  analysis confirmed the purity of deposited samples. ...

An energetic micro-initiator through integrating Al/Ni nano-multilayers with Cu film bridge was investigated in this study. The Cu film bridge was initially fabricated with wet etching, and Al/Ni nano-multilayers were alternately deposited on the surface of Cu film bridge by magnetron sputtering. The periodic layer structure of Al/Ni nano-multilayers was verified by scanning electron microscopy...

Co/Ni multilayers display perpendicular magnetic anisotropy and have applications in magnetic devices that could lead to a large increase in the density of magnetic storage. Co/Ni 10-(2 A Co/ 8A Ni) and 10-(2 A Co/ 4A Ni) multilayers were deposited with ion beam sputtering on either ion beam sputtered copper or direct current magnetron sputtered gold buffer layers of various thicknesses. The ef...

The sputter deposited ~Pt/Co/Pt/Ni! multilayer films were studied as possible alternative low Curie temperature multilayers for magneto-optical recording. The Curie temperatures of these multilayers were found to be between 150 and 300 °C, which are much lower than those of Co/Pt multilayers or ~Co,Ni!/Pt multilayers. The coercivities of these multilayers were between 450 and 800 Oe. The Kerr s...

Nmi multilayers are used as supermirrors for neutron guides. These multilayers are submitted to neutron irradiation. In order to determine the effect of irradiation on supermirrors performances we studied Ni/'Ti multilayers irradiated with thermal neutrons. We present here the results obtained by neutron reflectivity, X-ray diffraction and EXAFS on one sample. It has been found that the supermi...

Control of interfacial roughness and chemical mixing is critical in nanomaterials. For example, multilayers composed of ;20 Å conductive layer sandwiched between two ;50 Å ferromagnetic layers can exhibit giant magnetoresistance ~GMR!. This property has caused a tremendous recent increase in hard disk storage capacity, and can potentially result in a new generation of nonvolatile magnetic rando...

First-principles calculations have been performed in order to determine effective exchange integrals between strongly and weakly exchange-biased Co monolayers in the modulated CoCu 2 /CoCu n superlattices. For 3 ≤ n ≤ 6 it has been found that the respective exchange integrals have opposite signs and differ for n = 4 from each other by one order of magnitude and for n = 4 still by a factor of ∼ ...
