  We investigate theoretically the interplay of proximity effects due to the
presence of a superconductor and normal ferromagnetic leads on the formation of
the spintronic quadrupolar exchange field in a large-spin molecule. We show
that the spintronic anisotropy can be enhanced by a few orders of magnitude,
and tuned by changing the strength of coupling to the superconductor.
Especially large anisotropy is generated in the vicinity of the charge parity
changing transition of the molecule. We also provide predictions of measurable
spectral properties being the hallmarks of these phenomena.
