Fe3O4 is a promising candidate for spintronics. As an inert oxygen supplier, YSZ (Yttria Stabilized Zirconia) is an ideal substrate for optimizing the growth parameters of Fe3O4 on it. This project encompasses the growth and characterization of magnetite on YSZ substrates. Magnetite growth parameters were optimized for PLD and a temperature series of samples produced for further study. Using AFM and XRR, the surface morphology of the Fe3O4 is examined. XRD is used to check the crystallinity and calculate the out-of-plane lattice constant of the thin films. By measuring magnetic and electric properties, we study the metal-insulator Verwey transition temperature which is sensitive to the magnetite stoichiometry. Analyzing the magnetoresistance in-plane and out-of-plane is also an indicator of the crystalline arrangement of magnetite on YSZ substrates. The optimized growth parameters will be used to grow magnetite on strontium titanate substrates and the properties of Fe3O4 will here be tuned by annealing and applied electric field and characterized using XRD, GALAXI and SQUID in the framework of my masters thesis. |
