ABSTRACT
As we mentioned in Section 2.5, magnetization oscillations known
as a ferromagnetic resonance arise from the precessional motion
of the magnetization of a ferromagnetic material when an external
DC magnetic field with specific (for each external field) frequency is
applied in the presence of microwave pump field perpendicular to
it. Since magnetic tunnel junctions are composed of ferromagnetic
electrodes, it is possible to detect such resonance peaks if the spectra
of their voltage fluctuations are measured up to a few tens of GHz.
