Title: Single crystal growth and characterization of Na{sub x}Ln{sub 1−x}MoO{sub 4}, Ln=La, Ce, Pr, Nd, Sm, and Eu (x=0.397–0.499)

Abstract

Single crystals of La{sub 0.516(3)}Na{sub 0.484(3)}MoO{sub 4}, Ce{sub 0.512(2)}Na{sub 0.488(2)}MoO{sub 4}, Pr{sub 0.502(2)}Na{sub 0.498(2)}MoO{sub 4,} Nd{sub 0.501(2)}Na{sub 0.499(2)}MoO{sub 4}, Sm{sub 0.509(2)}Na{sub 0.491(2)}MoO{sub 4}, and Eu{sub 0.603(2)}Na{sub 0.397(2)}MoO{sub 4} were grown for the first time out of an alkali metal halide eutectic flux. All compounds crystallize in the tetragonal space group I4{sub 1}/a. UV/Vis measurements show the presence of an absorption edge for all compounds except Eu{sub 0.603(2)}Na{sub 0.397(2)}MoO{sub 4}. The temperature dependence of the magnetic susceptibility was measured for all compounds and found to be paramagnetic across the entire 2–300 K temperature range measured. - Graphical abstract: Single crystals of La{sub 0.516(3)}Na{sub 0.484(3)}MoO{sub 4}, Ce{sub 0.512(2)}Na{sub 0.488(2)}MoO{sub 4}, Pr{sub 0.502(2)}Na{sub 0.498(2)}MoO{sub 4,} Nd{sub 0.501(2)}Na{sub 0.499(2)}MoO{sub 4}, Sm{sub 0.509(2)}Na{sub 0.491(2)}MoO{sub 4}, and Eu{sub 0.603(2)}Na{sub 0.397(2)}MoO{sub 4} were grown for the first time out of an alkali metal halide eutectic flux.
