“…Ordered double perovskites, A 2 BB′O 6 , are a good baseline structure for determining suitable HM material candidates, because there are a variety of combinations for substituting the A-site or B-site elements. In previous research, HM compounds were found, such as Sr 2 FeWO 6 [6], Sr 2 FeReO6 [15,16], Sr 2 MnMoO6 [16], Sr 2 CuOsO 6 [17], Sr 2 VOsO 6 [18], Sr 2 NiRuO 6 [19], Sr 2 FeTiO 6 [20], Sr 2 CrMoO 6 [12,21], Sr 2 CoMoO 6 [12], Sr 2 CrReO 6 [11,15] and Sr 2 CrWO 6 [14,22] for the same ion Sr on the A-site with different combinations of B-site elements. Sr 2 MnMoO 6 [8] and Ba 2 MnMoO 6 [23] represent A-site substitution with fixed B-site elements.…”
