Magnetic Resonance Studies of the Fundamental Spin-Wave Modes in Individual Submicron Cu/NiFe/Cu Perpendicularly Magnetized Disks
Year: 2007
Type: article
Abstract: Spin-wave spectra of perpendicularly magnetized disks consisting of a 100 nm permalloy layer sandwiched between two Cu layers of 30 nm are measured individually by a magnetic resonance force microscope. Using 3D micromagnetic simulations, it is demonstrated that, for submicron-size diameters, the lowest energy spin-wave mode of the saturated state is not spatially uniform, but rather is localized at the center of the Py/Cu interfaces in the region of the minimum demagnetizing field.
