Abstract:
It is shown that the signal-to-noise ratio in the magnetic stochastic resonance of single-domain ferromagnetic
nanoparticles having cubic anisotropy exhibits a strong intrinsic dependence on the decay rate a of the Larmor
precession. This dependence sprecession aided relaxationd is due to coupling between longitudinal relaxation
and transverse sprecessionald modes arising from the lack of axial symmetry. It is most pronounced in the
intermediate-to-low damping sKramers turnoverd region 0.1,a,1. The effect which does not exist for axially
symmetric potentials may be used to determine a.
