“…The arrows on atoms in the figures indicate the spin directions in ground states. For Ba 2 MnWO 6 , the spin directions are parallel on (111) plane and anti-parallel between neighboring (111) planes, forming AFM magnetic structure [22]. The unit cell is doubled due to this magnetic structure.…”

The electronic structures of double perovskites Ba 2 MnWO 6 and Ba 2 MnReO 6 are studied by using firstprinciples linear muffin-tin orbital method. The ground magnetic phases for the two compounds are found to be antiferromagnetic and ferrimagnetic, respectively, in agreement with experimental results. Barium atoms in both of the compounds show obvious ionic characters while very strong hybridizations are found among the states of Mn 3d -O 2p -W(Re) 5d. Metallic band structure is obtained for Ba 2 MnReO 6 even though on-site Coulomb interaction (LSDA+U method) is considered for Mn 3d and Re 5d states. A finite energy gap appears in the compound only when spin -orbital coupling on Re ions is also taken into account. This semiconducting band structure can explain well the curve of resistivity versus temperature observed in experiment for ferrimagnetic Ba 2 MnReO 6 .

Control of cation ordering in ABX3 perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA′BB′O6 double double perovskites, where both A and B sites have 1:1 cation order, to (A0.5A′0.5)2BB′O6 double perovskites with fully disordered A/A′ cations can be achieved under pressure in CaMnMnWO6 and SmMnMnTaO6, enabling both polymorphs of each material to be recovered. This leads to a dramatic switch of magnetic properties from ferrimagnetic order in double double perovskite CaMnMnWO6 to spin glass behaviour in the highly frustrated double perovskite polymorph. Comparison of double double and double perovskite polymorphs of other materials will enable effects of cation order and disorder on other properties such as ferroelectricity and conductivity to be explored.
