dc.description.abstractA comparative study of the nuclear and magnetic structure of La0.57-x,,CexCa0.33Mn03 (X = 0, 0.05, 0.10, 0.20) perovskite (x =0, 0.05, 0.10, and 0.20) is reported. When the lanthanum is partially substituted by yttrium or a rare earth such as Pr or Tb, the structural cation disorder has been shown to lead to different and interesting phenomena, depending on the nature of the substitute cation (in general isovalent one in Ce-doped manganites, Ce3+ and Ce4+ species are able to coexist adding an extra source of disorder. This statement is supported by previous x-ray absorption (XAS) experiments[1]. Magnetic measurements made on these compounds have shown that Ce-doping introduces strong magnetic frustration in the spin system[2]. Furthermore, the magnetic behavior of La0.47CeO.2OCa0.33Mn03.OO observed[2] has been to be closely correlated with the electronic transport properties. To achieve a better understanding the nature of the magnetic phase in these Ce-doped manganites, we have carried out systematic neutron of powder diffraction experiments. Both nuclear and magnetic structure are studied as a function of temperature and cerium content. © 2005 The Authorsen_AU
