Özet

Re2O3 (Re = Er,Gd, Ho, Y and Yb) was prepared by sol-gel synthesis using metal-organic precursors. Residual stress and microstructure in the Re2O3 buffer layers were investigated as a function of temperature and film thickness. Textured Re2O3 buffer layers were grown on biaxially textured-Ni (100) substrates using chemical solution deposition. Films were annealed at 1150 degrees C under a flowing 4% H-2-Ar gas. X-ray diffraction of the buffers showed strong out-of-plane orientation on Ni tape. Residual stress in various thicknesses of buffer layers was calculated. The surface morphologies and microstructure of all samples were characterized using SEM and AFM.
