Microwave Resonances in Nanogranular (Fe



Massimo Pasquale, Sergio Perero, Giorgio Bertotti, Pavel Kabos


We have analyzed the microwave behavior of soft nanogranular (Fe0.7uCo0.3u)71uB22uNi films with thickness of 136, 195 and 236 nm which present a dc relative permeability from 60 to 280, a resistivity of 8 to 9×107d Ω}m and a zero-field double ferromagnetic resonance peak at frequencies ranging from 3.8 GHz up to 8.35 GHz. The high frequency and large line-width of the observed resonances allows for possible applications in microwave absorbers in a frequency range extending from 6 to 10 GHz.
