Além dos efeitos da geometria finita e aprisionamento, foi analisado o comportamento do sistema ao variar parâmetros externos como força de transporte e campo magnético. Os sistemas simulados correspondem a supercondutores bidimensionais, finitos na direção transversal e infinitos na direção longitudinal. A descrição das interações existentes no sistema pôde ser feita através de um conjunto de equações de Langevin, as quais foram resolvidas utilizando a técnica de Dinâmica Molecular. As soluções destas equações permitiram, dentre outros resultados, a obtenção das trajetórias e velocidades dos vórtices. Através das trajetórias, foi possível determinar o comportamento dinâmico das linhas de fluxo, e através das velocidades, os valores de força crítica. Para obter as posições iniciais dos vórtices, foi utilizado um algoritmo de Recozimento Simulado Generalizado (Generalized Simulated Annealing), o qual permitiu obter as configurações de menor energia do sistema. Os cálculos realizados foram feitos para 154 diferentes sistemas, que consistiram na análise do comportamento das interações neles existentes ao variar o campo magnético externo (H) aplicado nas amostras, bem como na a...

In addition to the effects of finite geometry and pinning, we analyze system behavior by varying external parameters such as transport force and magnetic field. The simulated systems corresponds a two-dimensional superconductor, finite in the transverse direction and infinite in the longitudinal direction. The description of the interactions existing in the system can be made via a set of Langevin equations which were solved using Molecular Dynamics techniques. The solutions of these equations allowed, among other results, to obtain the trajectories and velocities of the vortices. Through the trajectories, it was possible to determine the dynamic behavior of the vortex lines, and through the velocities, the values of critical force. To obtain the initial positions of the vortices, we use a Generalized Simulated Annealing algorithm, which sought the settings of the lower energy system. Our calculations were made for 154 different systems, consisting in analyzing the interaction behavior contained in the systems by varying the external magnetic field (H) applied in the samples and the analysis of size effects of superconducting tapes using different arrays and parts of arrays of pinning centers. To study the influence of the applied magnetic field, a scan was taken with... (Complete abstract click electronic access below) / Mestre
