Crystal growth and magnetic properties of lanthanide-containing osmium double perovskites, Ln2NaOsO6 (Ln = La, Pr, Nd).
A series of double perovskite oxides, Ln(2)NaOsO(6) (Ln = La, Pr, Nd), has been prepared as single crystals from acidic molten NaOH. All three oxides crystallize in the monoclinic space group P2(1)/n (Glazer tilt system #10, a(-)a(-)b(+)), forming a 1:1 ordered rock salt lattice of the Na(+) and Os(5+) cations. Magnetic susceptibility measurements show evidence of antiferromagnetic correlations in La(2)NaOsO(6) and of a spin-flop transition from an antiferromagnetic to ferromagnetic-like state in both Pr(2)NaOsO(6) and Nd(2)NaOsO(6).
