| description | We report structural analysis, surface morphology, magnetic ordering, dielectric response, optical feature and the electronic structure of the Dy2BiFeO6 novel complex perovskite. The samples were produced by the standard solid-state reaction recipe. Crystallographic analysis was performed by Rietveld refinement of experimental X-ray diffraction patterns. Results show that this material crystallizes in a perovskite with orthorhombic structure, which corresponds to the Pnma (#62) space group. From the Curie-Weiss fitting on the curve of susceptibility as a function of temperature we establish that the ordering corresponds to a paramagnetic-antiferromagnetic transition, with a Weiss temperature q=-18,5 K, which is compatible with the behavior of the inverse of susceptibility as a function of temperature, and a Néel temperatura TN=50,8 K. The Curie constant allowed for us to obtain an effective magnetic moment of 15,7 mB. The result of magnetization as a function of the applied field, measured at T=50 K, shows a magnetic hysteresis behavior that corroborate the magnetic ordering present for this temperature value. Measurements of the dielectric constant as a function of applied frequencies at room temperature give as a result a high relative dielectric constant (e=780). The reflectance curve as a function of the wavelength reveals the typical behavior of a double perovskite-like material and permits to obtain the energy gap 2,74 eV, which is characteristic of a semiconductor material. |

En este trabajo reportamos el análisis estructural, morfología superficial, ordenamiento magnético, respuesta dieléctrica y característica óptica de la nueva perovskita compleja Dy2BiFeO6. Las muestras fueron producidas mediante reacción de estado sólido. El análisis cristalográfico fue realizado a través de refinamiento Rietveld de los patrones experimentales de rayos X. Los resultados muestran que este material cristaliza en una perovskita ortorrómbica correspondiente al grupo espacial Pnma (#62). Por medio del ajuste de Curie-Weiss a la respuesta de la susceptibilidad magnética en función de la temperatura se estableció que el ordenamiento magnético se relaciona con una transición paramagnético-antiferromagnético con una temperatura de Weiss θ=-18,5 K, la cual es acorde con el comportamiento del inverso de la susceptibilidad en función de la temperatura, y una temperatura de Néel TN=50,8 K. La constante de Curie permitió determinar un momento magnético efectivo de 15,7 μB. Medidas de magnetización en función del campo aplicado a T=50 K, muestran un débil comportamiento histerético, que corrobora el ordenamiento magnético presente a esa temperatura. Mediciones de la constante dieléctrica en función de la frecuencia aplicada a temperatura ambiente dan como resultado una alta constante dieléctrica relativa a bajas frecuencias (ε=780). La curva de reflectancia en función de la longitud de onda revela el comportamiento típico de un material de tipo perovskita doble y permite la obtención de la brecha de energía de 2,74 eV característico de un material semiconductor.
