AB  - We present a study of the structural and chemical properties of the magnetic insulator NiFe2O4 on conductive Nb-dopedSrTiO3(001) substrates. Special regard is given to the dependence of the thin film properties on the O2:Ar ratio during pulsed laserdeposition. By using stoichiometric NiFe2O4 target material and varying the O2 partial pressure from 0% to 100%, we find a nonzerooxygen threshold for heteroepitaxial growth and a stoichiometric Fe:Ni cation distribution. Moreover, our study clearly demonstratesthat NiFe2O4 thin films grow with high quality over a wide range of oxygen partial pressures. These optimized NiFe2O4/SrTiO3heterostructures are envisioned as efficient spin filter tunnel contacts for room temperature application.
