Abstract information

English title:	Evaluation of the electrical and magnetic properties of the Bi1-xYbxFeO3 (0<x<0.1) system
Spanish title:	Evaluaci�n de las propiedades el�ctricas y magn�ticas del sistema Bi1-xYbxFeO3 (0<x<0.1)
English abstract:	The BiFe1-xYbxO3 (x=0.00, 0.02, 0.04, 0.05, 0.06 and 0.10) system was produced by the standard solid-state reaction method. The structural properties at room temperature were studied by Rietveld analysis of X-ray diffraction patterns, these reveal that samples crystallizes in majoritarian BiFe1-xYbxO3 phase with trigonal R 3 m (#160) space group. Magnetic measurements as a function of temperature performed on vibrating magnetometer signals two magnetic behaviors, first one for x<0.05 and a second one for x>0.06. The resistivity measurements as a function of temperature exhibits insulating behavior. Polarization curves were collected at room temperature displaying a ferroelectric signature.
Spanish abstract:	El sistema BiFe1-xYbxO3 (x=0,00, 0,02, 0,04, 0,05, 0,06 y 0,10) se produjo mediante el m�todo est�ndar de reacci�n en estado s�lido. Las propiedades estructurales a temperatura ambiente se estudiaron mediante an�lisis Rietveld de patrones de difracci�n de rayos X, estos revelan que las muestras cristalizan en fase mayoritaria BiFe1-xYbxO3 con grupo espacial trigonal R 3 m (#160). Las medidas magn�ticas en funci�n de la temperatura realizadas en un magnet�metro vibratorio se�alan dos comportamientos magn�ticos, el primero para x<0.05 y el segundo para x>0.06. Las mediciones de resistividad en funci�n de la temperatura exhiben un comportamiento aislante. Las curvas de polarizaci�n se recogieron a temperatura ambiente mostrando una firma ferroel�ctrica.
