## Description

- description: A2CuBʹO6 double perovskites with A = Sr and Ba and Bʹ = W, Te, and
    Mo have received a lot of attention in the literature as material candidates for
    the spin-liquid ground state and frustrated spin lattices. However, Ca analogues
    have not been reported yet. In this work, the Ca2CuWO6 double perovskite was synthesized
    by a high-pressure, high-temperature method at 6 GPa and between 1370 and 2020
    K. The crystal structure was studied by synchrotron powder X-ray diffraction between
    100 K and 1000 K. Ca2CuWO6 crystallizes in the triclinic space group P-1 between
    100 K and 1000 K with the onset of partial decomposition above 750 K. Room-temperature
    lattice parameters are a = 5.68435 Å, b = 7.51261 Å, c = 5.49548 Å, a = 90.0703,
    b = 94.7634, and g = 90.2311. Ca2CuWO6 demonstrates low-dimensional magnetic properties
    with the broad maximum of the magnetic susceptibility around 60 K caused by the
    dominant second-neighbor interactions within the deformed square planes of the
    Cu2+ ions. A long-range antiferromagnetic order takes place at TN = 32 K. A magnetic
    field-induced transition was observed at 28 kOe (at 2 K and 5 K), 29 kOe (at 10
    K), 30 kOe (at 15 K), 32 kOe (at 20 K), and 36 kOe (at 25 K). Solid solutions
    Ca2-xSrxCuWO6 with x = 0.5, 1, and 1.5 were also prepared. The x = 0.5 and 1 samples
    crystallize in the space group P-1 at room temperature, while the x = 1.5 sample
    has monoclinic symmetry (space group P21/n). They also show low-dimensional magnetic
    behavior, TN = 32–34 K, and magnetic field-induced transitions.
