Magnetic anisotropy of epitaxial zinc ferrite thin films grown by pulsed laser deposition

► Normal spinel ZnFe2O4 gained up to now not much attention. ► Recently, semiconducting ZnFe2O4 thin films were established. ► Magnetic anisotropy of ZnFe2O4 thin films on SrTiO3 was shown. ► Anisotropy was measured by ferromagnetic resonance. ► Modeling of anisotropy constants and magnetic activation volume
