Theoretical calculations. a Calculated band structure of the STO/PZT heterostructure with Ueff =  2.3 eV for Ti and Zr d-orbitals. The majority-spin and minority-spin bands are represented by black solid and red dashed lines, respectively. b The squared wave-function of the state that crosses the Fermi level. c Atom-resolved DOS of the STO/PZT heterostructure. The vertical dashed line at E = 0 represents the position of the Fermi level. Blue and red colors denote O-2p and Ti-3d contributions, respectively. d The planar-average of spin density of the STO/PZT heterostructure along the polarization (P) axis. The corresponding atomic structure is shown in the left side
