Partículas de SrM, obtenidas por el método cerámico tradicional, fueron embebidas en una matriz polimérica termoplástica ferroeléctrica de PLA. El estudio estructural y magnético fue realizado usando las técnicas experimentales de difracción de rayos X y magnetometría vibracional, respectivamente. Para la determinación de las fases presentes en cada muestra se utilizó el método de Hanawalt a través del programa Match-3, &#8220;Phase Identification from Powder Diffraction&#8221;. Los resultados sugieren la coexistencia de ambas fases de forma independiente. Para el sistema cerámico los parámetros de la red varían muy poco de la fase individual al compuesto. Las propiedades magnéticas del sistema están moduladas en función de las concentraciones de las fases constituyentes y por la naturaleza de las interacciones magnéticas entre las mismas.]]></p></abstract>

SrM particles, obtained by the traditional ceramic method, were embedded in a PLA ferroelectric thermoplastic polymeric matrix. The structural and magnetic study was carried out using the experimental techniques of X-ray diffraction and vibrational magnetometry, respectively. To determine the phases present in each sample, the Hanawalt method was used through the Match-3! program "Phase Identification from Powder Diffraction". The results suggest the coexistence of both phases independently. For the ceramic system the parameters of the crystal lattice vary very little from the individual phase to the composite. The magnetic properties of the system are modulated as a function of the concentrations of the constituent phases and by the nature of the energetic and magnetic interactions between them.]]></p></abstract>
