Journal ArticleDOI
Stokes-anti-stokes brillouin intensity asymmetry of spin-wave modes in ferromagnetic films and multilayers
Roberto Zivieri,Paolo Vavassori,Loris Giovannini,F. Nizzoli,Eric E. Fullerton,M. Grimsditch,Vitali V. Metlushko +6 more
TL;DR: The Stokes-anti-Stokes intensity asymmetry, observed in Brillouin spectra from magnetic excitations, has been investigated experimentally and theoretically in single and multilayer films as mentioned in this paper.
Journal ArticleDOI
Enhanced Magneto-Optical Edge Excitation in Nanoscale Magnetic Disks.
Andreas Berger,R. Alcaraz de la Osa,A. K. Suszka,Matteo Pancaldi,José M. Saiz,Fernando Moreno,Hans Peter Oepen,Paolo Vavassori +7 more
TL;DR: Unexpected enhancements of the magneto-optical effect in ferromagnetic Permalloy disks of diameter D<400 nm are reported, which becomes increasingly pronounced for smaller D, reaching more than a 100% enhancement for D=100 nm samples.
Journal ArticleDOI
GMR as a function of temperature in FeAg granular samples: the effect of magnetic interactions
Federico Spizzo,E. Angeli,Diego Bisero,F. Ronconi,Paolo Vavassori,Paolo Maria Eugenio Icilio Allia,V. Selvaggini,Marco Coïsson,Paola Tiberto,Franco Vinai +9 more
TL;DR: In this paper, the giant magnetoresistance intensity as a function of iron concentration was investigated and the position of this maximum shifted progressively towards lower iron concentrations with decreasing temperature. But the authors did not consider the presence of magnetic interparticle interactions.
Journal ArticleDOI
Brillouin scattering and diffracted magneto-optical Kerr effect from arrays of dots and antidots (invited)
TL;DR: In this article, the magnetic properties of nanoarrays have been investigated using Brillouin scattering, magneto-optical Kerr effect (MOKE), and diffracted-MOKE (DMOKE) techniques.
Journal ArticleDOI
Evolution from multilayer to granular behavior via Cobalt layers fragmentation in Co/Cu multilayers
TL;DR: In this article, the structural evolution of Co(tCo)/Cu(4tCo) multilayers when tCo ranges from 12 to 2 A was analyzed by studying their magnetization and giant magnetoresistance.
