Descripción
Sumario:In this work, we present a comprehensive study on real-time monitoring the growth of epitaxial Co(x)Fe(3−x)O(4) thin films grown on SrTiO(3)(001) substrates via reactive molecular beam epitaxy. The growth process was monitored during evaporation by means of time resolved operando hard X-ray photoelectron spectroscopy (HAXPES). We prepared ultrathin ferrite films using different oxygen partial pressures, showing pure metallic, light oxidic, and cobalt ferrite-like growth. Additional X-ray diffraction measurements confirm HAXPES results.
