dc.description.abstractEste trabajo de grado se centra en el análisis del efecto Spin Seebeck (SSE) en sistemas ferromagnéticos, un fenómeno que ha adquirido relevancia en el campo de la espintrónica y la termoelectricidad. El efecto Spin Seebeck se refiere a la generación de un voltaje de espín en materiales ferromagnéticos cuando se aplica un gradiente de temperatura, lo que permite la conversión de energía térmica en energía eléctrica mediante la manipulación de los espines de los electrones. A lo largo del estudio y análisis se revisan los fundamentos teóricos del SSE, así como los modelos que describen su comportamiento bajo diferentes condiciones. Se presentan cálculos detallados que analizan la dependencia del voltaje de espín con variables como la temperatura.spa
dc.description.abstractThis degree work focuses on the analysis of the Spin Seebeck effect (SSE) in ferromagnetic systems, a phenomenon that has gained relevance in the field of spintronics and thermoelectricity. The Spin Seebeck effect refers to the generation of a spin voltage in ferromagnetic materials when a temperature gradient is applied, which allows the conversion of thermal energy into electrical energy through the manipulation of electron spins. Throughout the study and analysis, the theoretical foundations of the SSE are reviewed, as well as the models that describe its behavior under different conditions. Detailed calculations are presented that analyze the dependence of the spin voltage on variables such as temperatureeng
