一种双钙钛矿型自旋电子学材料Sr2FeReO6的制备方法
本发明公开一种双钙钛矿型自旋电子学材料Sr2FeReO6的制备方法，包括第一步，将碳酸锶、九水合硝酸铁、七氧化二铼原材料溶于稀硝酸中，加入络合剂和分散剂并搅拌形成溶胶；将溶胶于60~80℃加热搅拌，直至形成凝胶，100~300℃烘干制成干凝胶；将干凝胶研磨5~20分钟后，用5~15 MPa的压力压制成片，放入刚玉坩埚中在管式炉中于1000~1100℃氩气气氛下烧结24小时，冷却到室温后研磨压片，1000~1100℃氩气气氛烧结24小时，得到双钙钛矿型自旋电子学材料Sr2FeReO6。
The invention discloses a preparation method of a double perovskite type spintronics material Sr2FeReO6, which comprises the following steps: 1, dissolving raw materials of strontium carbonate, ferric nitrate nonahydrate and rhenium heptoxide in dilute nitric acid, adding a complexing agent and a dispersing agent, and stirring to form sol; heating and stirring the sol at 60-80 DEG C until gel is formed, and drying at 100-300 DEG C to prepare dry gel; and grinding the dried gel for 5-20 minutes, pressing the dried gel into tablets under the pressure of 5-15 MPa, putting the tablets into a corundum crucible, sintering the tablets in a tubular furnace in an argon atmosphere at 1000-1100 DEG C for 24 hours, cooling the tablets to room temperature, grinding the tablets, and sintering the tablets in the argon atmosphere at 1000-1100 DEG C for 24 hours to obtain the double perovskite spintronics material Sr2FeReO6.
