Description
Square lattices of permalloy rings with different inner diameters (Di) were fabricated by electron beam lithography and investigated by ferromagnetic resonance (FMR). Results reveal that FMR spectra are sensitive to the ring dimensions. A large shift of the uniform mode from 1200 to 1800 Oe, and a dramatic decrease in its intensity are observed as Di increases from 0 to 300 nm. Other resonance peaks at fields slightly below the uniform mode greatly increase in intensity and shift to lower field with increasing Di. An isolated resonance below 200 Oe is also observed. Possible reasons for these variations are discussed
