Abstract

A powder neutron diffraction study has been undertaken for the titled compounds at room temperature. Data were analyzed using the Rietveld method. With increasing Nd content the unit cell has been found to contract very slightly, which is in accordance with the ionic radii of La3+ and Nd3+.
