Abstract

We present a neutron powder-diffraction study of the monoclinic double perovskite systems Nd₂NaB^′O₆ (B ^′=Ru, Os), with magnetic atoms occupying both the A and B ^′ sites of the A₂BB^′O₆ structure. Our measurements reveal coupled spin ordering between the Nd and B^′ atoms with magnetic transition temperatures of 14.3(1) K for Nd₂NaRuO₆ and 16.2(2) K for Nd₂NaOsO ₆. There is a type-I antiferromagnetic structure associated with the Ru and Os sublattices, with the ferromagnetic planes stacked along the c axis and [110] direction respectively, while the Nd sublattices exhibit complex, canted antiferromagnetism with different spin arrangements in each system.
