I am interesting in the SQUID coupled to the nanomagnet. It has been already shown [1] that the SQUID feels the nanomagnet nicely, but otherwise the nanomagnet does not feel SQUID, because it produces too small magnetic fields.

If I can increase the influence of the fields made by SQUID to the nanomagnet, I probably can find some interesting dynamical regimes in this system.
