text: Vortex states in superconducting (SC) structures, their dynamics and ways
to manipulate them are topics of great interest. We report a new method of magnetic
force microscopy (MFM) that allows the study of vortex states in mesoscopic SC
samples. For the case of a SC ring, which is biased to a half-integer flux quantum,
the flux modulation through the ring caused by the motion of the magnetic tip
drives the ring between two consecutive fluxoid states. The corresponding current
switching in the ring produces strong position-dependent forces on the cantilever.
In the regime where the frequency of the thermally activated jumps between fluxoid
states is close to the frequency of the cantilever, large changes in the cantilever
frequency and dissipation are observed. This effect may be understood as a stochastic
resonance (SR) process. These changes in the cantilever’s mechanical properties
are used to “image” the barrier energies between fluxoid states. Additionally,
SR imaging of the barrier energies are used to study the effect of the locally
applied magnetic field from the MFM tip on the barrier heights. We report the
results of measurements for Al rings. Further, the same imaging technique can
be applied to more sophisticated SC structures such as arrays of Josephson junctions.
