| description |
En este trabajo, se estudiaron y analizaron diversas propiedades del compuesto La(5/8-x)Pr_xCa(3/8)MnO_3 (LPCMO), una variante de manganita reconocida por su amplia gama de fases magnéticas que influyen significativamente en las características de transporte del material. Se sintetizaron tres muestras con diferentes dopajes: X = 0.35, X = 0.4 y X = 0.45, con el propósito principal de comprender la coexistencia entre las fases ferromagnéticas metálicas (FMM) y antiferromagnéticas aislantes (AFI). La caracterización inició con la difracción de rayos X de la primera muestra, revelando una fase y parámetros de red cristalina que se aproximan a los valores reportados. La caracterización magnética se llevó a cabo mediante curvas de histéresis, exhibiendo un comportamiento ferromagnético debido a la contribución de dominios FMM, y una envolvente influenciada por la fase AFI, generando un bajo campo coercitivo (menor a 200 Oe). Las curvas de magnetización frente a la temperatura permitieron identificar la temperatura de Curie (Tc), además de evidenciar transiciones discontinuas para el dopaje de 0.4. Asimismo, se realizaron diagramas FORC, corroborando las contribuciones identificadas en las curvas de histéresis, y destacando regiones con alta interacción y coercitividad, sugiriendo la existencia de un acoplamiento en la interfaz de los dominios. Las mediciones de resistencia frente a la temperatura y al campo, para el dopaje de 0.4, revelaron transiciones discontinuas tanto aleatorias como bien definidas. Finalmente, se llevó a cabo una simulación computacional utilizando el Random Field Ising Model (RFIM), modificando parámetros análogos a la red cristalina y el dopaje. Esta simulación logró reproducir curvas similares a las de magnetización frente a la temperatura, histéresis y una envolvente superparamagnética debido al antiferromagnetismo. |

Se sintetizaron tres muestras con diferentes dopajes: X = 0.35, X = 0.4 y X = 0.45, con el propósito principal de comprender la coexistencia entre las fases ferromagnéticas metálicas (FMM) y antiferromagnéticas aislantes (AFI).

Three samples with different doping levels were synthesized: X = 0.35, X = 0.4, and X = 0.45, with the main purpose of understanding the coexistence between ferromagnetic metallic (FMM) and antiferromagnetic insulating (AFI) phases. The characterization began with X-ray diffraction of the first sample, revealing a phase and crystalline lattice parameters that approximate the reported values. The magnetic characterization was carried out through hysteresis curves, exhibiting ferromagnetic behavior due to the contribution of FMM domains, and an envelope influenced by the AFI phase, generating a low coercive field (less than 200 Oe). The magnetization versus temperature curves allowed the identification of the Curie temperature (Tc), in addition to evidencing discontinuous transitions for the doping level of 0.4. Furthermore, FORC diagrams were performed, corroborating the contributions identified in the hysteresis curves, and highlighting regions with high interaction and coercivity, suggesting the existence of coupling at the domain interfaces. The resistance measurements as a function of temperature and field, for the doping level of 0.4, revealed both random and well-defined discontinuous transitions. Finally, a computational simulation using the Random Field Ising Model (RFIM) was carried out, modifying parameters analogous to the crystalline lattice and doping. This simulation managed to reproduce curves similar to those of magnetization versus temperature, hysteresis, and a superparamagnetic envelope due to antiferromagnetism.Pregrado66 páginasapplication/pdfspaUniversidad de los AndesFísicaFacultad de CienciasDepartamento de Físicahttps://repositorio.uniandes.edu.co/static/pdf/aceptacion_uso_es.pdfinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Dinámica de coexistencia de fases en manganitas de Lantano dopadas con Calcio y PraseodimioTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_7a1fTexthttp://purl.org/redcol/resource_type/TPLPCMOManganitasFases magnéticasFerromagnético metálicoAntifferomagnético aislanteHistéresisTemperatura de CurieFORCPercolaciónCoexistencia de fasesFísicaSiming Wang, Juan Gabriel Ramírez, and Ivan K.
