We propose to use ferromagnetic resonance force microscopy to measure the dissipative term that enters in the equation of motion for the magnetization vector. The experiments were carried out at microwave frequencies on a ...

We compare mechanically detected ferromagnetic resonance spectra for different separations h between the magnetic tip and sample surface. When the bias field generated by the tip is smaller than a few hundred gauss, the ...

The ferromagnetic resonance spectrum of a normally magnetized yttrium-iron-garnet disk, with thickness of 4.75 μm and radius of 80 μm, is measured at room temperature both by magnetic resonance force microscopy and by ...
