A study of the magnon contribution to the properties of the [Ni1−xFex/Cu] alloy super-lattices

Magnetic Studies of Spin Wave Excitations in Ni/Cu Multilayers

“…Magnetic multilayers with artificial periodicity constitute a topic of active investigations, both on the fundamental research level as well as on the applied one. Several experimental and theoretical studies were carried out to understand the origin of the various interactions existing in this kind of systems, in particular in the interface since it presents magnetic properties different those of bulk [1][2][3][4]. Since multilayers are inherently metastable material on a nanometer scale, the introduction of the period, the number of layers and the relative thicknesses of the magnetic layers and nonmagnetic layers in multilayers will result in many interesting properties, which are sensitive to the microstructures [5][6][7][8].…”
