Study of RF-to-DC conversion using spintronics devices

This internship was carried out in the Spintec laboratory, in the Microwave devices group. The purpose of this project is to characterize the dynamic behavior of Metallic Tunnel Junctions, and to demonstrate their ability to be used as RF-to-DC conversion components. A set of different devices were built for this project and were statically and dynamically characterize to observe the detection phenomenon. This project showed the dependence between the conversion and the different external parameters and junction configuration. The results show that the best RF-to-DC conversion happens for the devices with the smallest diameters, under a high in-plane or out-of-plane external magnetic field, and a high current to excite the layers.
