Abstract : In the period of this grant we have been working on several topics such as the classical and quantum theory of spin waves of magnets at the nanoscale; novel magnetic materials and interfaces; domain wall dynamics; and inter-element interactions. There are fundamental questions in these topics that we addressed, such as the effects of geometry and roughness on the reflection and transmission of spin waves on waveguides; mechanisms for controlling the anisotropy of nanometric samples; and the preparation of nano-elements with interesting and promising magnetic and transport properties by combining different techniques such as chemical synthesis, self-organized methods, sputtering, lithography and atomic layer deposition (ALD). In thin films, we have been working on the control of magnetic anisotropy in magnetic multilayers in order to obtain spin valves and enhance the magnetoresistance and Hall Effect. We also started to perform e-bean lithography in order to reduce the dimensions of the nanoelements, and then improve the performance of the systems aiming to possible sensor devices.
