Atomic ordering in the LaFe0.5Mn0.5O3 solid solution film

LaFe0.5Mn0.5O3 solid solution films have been formed on SrTiO3 (111) substr ates using a pulsed laser deposition technique and their magnetic propertie s have been examined. The films showed ferromagnetic (or ferromagnetic) beh avior with a Curie temperature of 380 K and the saturation magnetization wa s estimated to be about 1.5 mu (B) per magnetic ion site (B site). The x-ra y photoemission spectra indicated that this behavior was due to the partial ordering of magnetic ions (Fe and Mn ions) which is caused by the charge d isproportion between Fe and Mn ions under the film formation conditions.
