Magnetic and transport properties of Ag/Co 90Fe 10 granular multilayers

Mostrar todas las versiones(3)

We report experimental results on the magnetic and transport properties of Ag/Co 90Fe 10 multilayers with variable Ag and Co 90Fe 10 thicknesses. The magnetism samples was characterized by magnetization measurements and ferromagnetic resonance spectroscopy. These measurements show that the magnetic...
