Article title

Mechanical magnetometry of Cobalt nanospheres
deposited by focused electron beam at the tip of
ultra-soft cantilevers


Title variants

Languages of publication



Using focused-electron-beam-induced
deposition, Cobalt magnetic nanospheres with diameter
ranging between 100 nm and 300 nm are grown at the tip
of ultra-soft cantilevers. By monitoring the mechanical
resonance frequency of the cantilever as a function of
the applied magnetic field, the hysteresis curve of these
individual nanospheres are measured. This enables the
evaluation of their saturation magnetization, found to
be around 430 emu/cm3 independent of the size of the
particle, and to infer that the magnetic vortex state is
the equilibrium configuration of these nanospheres at
remanence.SEM image of a 200 nm Co nanosphere grown at
