A stochastic model for simulating the FC and ZFC processes of FE and PY particles / Um modelo estocástico para a realização de simulações dos processos de FC e ZFC de partículas de FE e PY

Abstract

 We performed computer simulations on the nanoscopic scale to find the energy distribution of the anisotropic barrier of Fe and Py nanoparticles. We investigated the physical properties of these magnetic nanoparticles for potential application in the catalysis of coal liquefaction. We examined the characteristics of the microstructure of these fundamental nanoparticles to optimize the ability to catalyze the breakdown of carbon-carbon bonds. We reported our results for nanoparticles, cubic, Fe and Py. We constructed ZFC and FC curves to determine the distribution of the blocking temperature. The ZFC and FC curves exhibit the same blocking temperature, behavior dependent on the magnitude of the applied magnetic field. Finite-scale scale effects determinant for technological applications are reported. Keywords: Nanoparticles, Magnetism, Catalyst, Liquefaction, Coal.
