Estudio de propiedades magnéticas en películas ultra delgadas

T-MOKE and VSM systems were used to characterize thin films of cobalt oxide (CoO) alloy with thicknesses of 2.5 nm (CoO) and 5 nm (MultiCoO). Measurements were conducted for fields below 1000 Oe in a temperature range from 30K to 450K. Variations in the hysteresis curves with changes in temperature...

description T-MOKE and VSM systems were used to characterize thin films of cobalt oxide (CoO) alloy with thicknesses of 2.5 nm (CoO) and 5 nm (MultiCoO). Measurements were conducted for fields below 1000 Oe in a temperature range from 30K to 450K. Variations in the hysteresis curves with changes in temperature and magnetic field were observed. Magnetic properties, such as coercive field and remanence, indicated a phase transition in the range of 147K to 150K, and a decrease in remanence at very high or low temperatures. Both systems showed similar trends between 150K and 300K, although differences were found at lower temperatures due to VSM limitations. The FC and ZFC measurements of the VSM system indicated minimal changes in magnetization above 200K. The effect of temperature on magnetic properties was significant in the T-MOKE system, so it is necessary to use precise techniques to ensure thermal stability.

Las mediciones se realizaron para campos inferiores a 1000 Oe en un rango de temperaturas de 30K a 450K. Se observaron variaciones en las curvas de histéresis con cambios de temperatura y campo magnético. Las propiedades magnéticas, como el campo coercitivo y la remanencia, indicaron una transición de fase en el rango de 147K a 150K, y una disminución de la remanencia a temperaturas muy altas o bajas. Ambos sistemas mostraron tendencias similares entre 150K y 300K, aunque se encontraron diferencias a temperaturas más bajas debido a las limitaciones del VSM. Las mediciones FC y ZFC del sistema VSM indicaron cambios mínimos en la magnetización por encima de los 200K. El efecto de la temperatura en las propiedades magnéticas fue significativo en el sistema T-MOKE, por lo que es necesario utilizar técnicas precisas para asegurar la estabilidad térmica.PregradoMateria condensada, baja dimensionalidad52 páginasapplication/pdfspaUniversidad de los AndesFísicaFacultad de CienciasDepartamento de FísicaAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Estudio de propiedades magnéticas en películas ultra delgadasTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_7a1fTexthttp://purl.org/redcol/resource_type/TPT-MOKEJunturas túnel magnéticasMagnetismoÓxido de CobaltoVSMCoercitividadRemanenceMTJFerromagnetismoMagnetismCobalt OxideCoercivityRemanenciaMagnetic tunnel junctionFísicaStångberg Valgeborg, F.
