title = "Broadband ferromagnetic resonance measurements of a micromagnetic disk array using a meander-line technique",
abstract = "A simple technique involving transmission through a copper-wire meander line is developed to study ferromagnetic resonance (FMR) in magnetic arrays. Using this technique, we carried out FMR measurements on a square array of submicrometer-size Permalloy magnetic disks for an external dc magnetic field parallel to the plane of the array, and found several magnetic excitation modes. The dominant mode obeys the Kittel formula for a plain film. The technique is suitable for studying the collective excitation modes in the magnetic nanoarrays over a broad range of frequencies.",

Schematic of the experimental setup (see text for details). FIG. 2. Transmitted signal vs magnetic field for different frequencies from 3 to 12 GHz (curves from top to bottom) at 100 K. The magnetic field was swept in one direction from − to + . FIG. 3. Magnetic field at which FMR occurs as a function of the microwave frequency at 100 K (scattered data). The data were taken with the magnetic field swept in both directions: from − to + and from + to − . The dominant mode is denoted by solid circles. The solid line is the same dependence according to the Kittel formula for parallel field for saturation magnetization M s = 875 emu / cm 3 . ",
