[ES]En este Trabajo de Fin de Grado se trata el tema del Micromagnetismo y la Espintr?nica. Las ideas y experimentos presentados se organizan en cuatro cap?tulos principales seguidos de un cap?tulo final en el que se exponen las conclusiones generales del trabajo. El primer cap?tulo consta de dos partes. La primera, es una introducci?n te?rica al Micromagnetismo que servir? de base para entender las simulaciones llevadas a cabo en los cap?tulos posteriores. Al final del capitulo tambi?n se hace una introducci?n te?rica a la Espintr?nica, revisando y comentando algunos de los principales experimentos realizados en este campo . En el segundo capitulo, se repasan brevemente los princiaples tipos de software, hardware y m?todos computacionales empleados en simulaciones micromagn?ticas. Los dos capitulas siguientes se corresponden a los problemas est?ndar 2 y 4. Estos problemas son de utilidad a la hora de iniciarse con simulaciones micromagn?ticas. El cap?tulo siguiente a los problemas est?ndar trata el fen?meno de la resonancia ferromagn?ti ca. Una vez obtenida cierta experiencia con los programas micromagn?ticos gracias alos problemas est?ndar, se simula una nanoesfera ferromagn?tica con el objetivo de identificar y estudiar el fen?meno de resonancia.
[EN]This work deals with the subject of Micromagnetism and Spintronics. The ideas and experiments are organized in four main chapters followed by a final chapter where the general conclusions of the work are stated. The first chapter is split in two parts. The first one, it's a theoretical introduction to Micromagnetism in order to provide a basis to understand the simulations exposed in next chapters. At the end of this chapter, a theoretical introduction to Spintronics is also conducted, reviewing and commenting on sorne of the main experiments carried out in this field. In the second chapter, a brief overview about the type of software, hardware and computational methods used in micromagnetic simulations is carried out. The next two chapters are related with the standard problems 2 and 4. These problems are useful to get started with micromagnetic simulations. The following chapter cope with the ferromagnetic resonance phenomena. Once we have certain exper ience with the programs by having the standard problems done, we are ready to simulate a ferromagnetic nanosphere in order to identify and study the resonance phenomenon.
