Abstract = {{Advances in growth technology of oxide materials allow single atomic
   layer control of heterostructures. In particular delta doping, a key
   materials' engineering tool in today's semiconductor technology, is now
   also available for oxides. Here we show that a fully
   electric-field-tunable spin-polarized and superconducting quasi-2D
   electron system (q2DES) can be artificially created by inserting a few
   unit cells of delta doping EuTiO3 at the interface between LaAlO3 and
   SrTiO3 oxides(1,2). Spin polarization emerges below the ferromagnetic
   transition temperature of the EuTiO3 layer (T-FM = 6-8 K) and is due to
   the exchange interaction between the magnetic moments of Eu-4f and of
   Ti-3d electrons. Moreover, in a large region of the phase diagram,
   superconductivity sets in from a ferromagnetic normal state. The
   occurrence of magnetic interactions, superconductivity and spin-orbit
   coupling in the same q2DES makes the LaAlO3/EuTiO3/SrTiO3 system an
   intriguing platform for the emergence of novel quantum phases in
   low-dimensional materials.}},
