The samples were produced by the solidstate reaction recipe. X-ray diffraction experiments and Rietveld refinement reveal that material crystallizes in a tetragonal complex perovskite (space group I4/m, number 87) with lattice parameters a=5.5858 °A and c=7.7518 A° . The magnetic properties were studied by a Quantum Design MPMS SQUID. From measurements of magnetization as a function of temperature, we determine the occurrence of a paramagnetic-antiferromagnetic transition with N´eel temperature TN=15.5 K. A Curie-Weiss fitting permitted to obtain the magnetic characteristic parameters. Curves of magnetization as a function of applied field show the magnetic hysteresis which is characteristic of magnetically ordered systems. Curves of electric polarization, including the application of voltages up to 560 V, evidence the ferroelectric character of material at room temperature. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030392012 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
