| Abstract: | In this work the perturbed angular correlation technique is used to locally monitor the epitaxy and thermal stability of the hafnium layer in a Zr/Hf/Zr multilayer. The studies reveal that the system is highly homogeneous and presents high epitaxy. Measurements at high temperatures show that no HfOx formation occurs up to 562 K but at this temperature the Hf layer is no longer oxygen-defect free. |
