Figure 2
Experimental (symbols) and calculated (line) neutron powder diffraction profiles for the Rietveld refinement of SrLnFeRuO6 (Ln = La, Nd, Pr) at room temperature, using a disordered orthorhombic (Pbnm) structural model. The upper (middle) markers indicate the position of the structural (magnetic) Bragg reflections and the lower markers the impurity (Nd3RuO7 and Pr3RuO7) Bragg reflections. The La3RuO7 impurity was excluded in order to guarantee convergence of the refinement. |
