ResumoAbstract Epitaxial thin films of spinel ZnFe 2 O 4 were grown along the 〈111〉 direction using laser-molecular beam epitaxy (laser-MBE) on an Al 2 O 3 (0001) single crystal substrate. Reflection high-energy electron diffraction (RHEED) patterns and its intensity oscillation indicate flat surface and keeping layer-by-layer growth modes of films. It was found that one cycle of intensity oscillation corresponded to oxygen layer growth: that is one magnetic Kagome layer, along the 〈111〉 direction. The produced ZnFe 2 O 4 film exhibited antiferromagnetism with a Neel temperature of 43 K.
