Direct measurement of the spin-lattice relaxation in a ferromagnet

Klein O.; Charbois V.; Naletov V.; Fermon C. (2004)

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 ...
Ferromagnetic resonance spectroscopy of parametric magnons excited by a four-wave process

Naletov V.; De Loubens G.; Charbois V.; Klein O.; Tiberkevich V.; Slavin A. (2007)

Using a magnetic resonance force microscope, we have performed ferromagnetic resonance spectroscopy of the parametric magnons created by a four-wave process. This is achieved by measuring the differential response to a ...
Influence of the magnetic tip in ferromagnetic resonance force microscopy

Charbois V.; Naletov V.; Youssef J.; Klein O. (2002)

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 ...
Measurement of the ferromagnetic relaxation in a micron-size sample

Klein O.; Charbois V.; Naletov V.; Fermon C. (2003)

It is shown that magnetic-resonance force microscopy can provide direct measurements of both the longitudinal and the transverse relaxation rates in a micron-size ferromagnetic sample. As a demonstration, we have applied ...
Mechanical detection of ferromagnetic resonance spectrum in a normally magnetized yttrium-iron-garnet disk

Charbois V.; Naletov V.; Ben Youssef J.; Klein O. (2002)

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 ...
Quantitative measurement of the ferromagnetic resonance signal by force detection

Naletov V.; Charbois V.; Klein O.; Fermon C. (2003)

The change of longitudinal magnetization which is associated with the resonant absorption of microwave power in a ferromagnetic crystal was studied. Magnetic resonance force microscope was used. It was found that the ...
