Hg(Re)1223的易磁化轴为c轴,这使得我们能够利用静磁场合成c轴取向的Hg(Re)1223多晶材料。在本研究中,c轴取向的Hg(Re)1223块材的制备在磁场中的粉浆浇注方法进行了尝试。将不同烧结条件下的Hg(Re)1223粉末在8 T条件下注浆成型,并在不同烧结条件下进行二次烧结。第二次烧结的块体在20 K和77 K的低场下的Jc分别为12 kA cm-2和2.4kA cm-2,这对于Hg(Re)1223烧结块体来说是相当高的值。
The easy magnetization axis of Hg(Re)1223 is c-axis, which enables us to synthesize c-axis oriented Hg(Re)1223 polycrystalline materials using a static magnetic field. In the present study, fabrication of the c-axis oriented Hg(Re)1223 bulks was attempted by the slip-casting method in magnetic field. The Hg(Re)1223 powder sintered under various conditions was slip-cast in 8 T and 2nd-sintered under various conditions. The 2nd-sintered bulks showed Jc~ 12 kA cm-2at 20 K and ~ 2.4kA cm-2at 77 K in low fields, which are quite high values for Hg(Re)1223 sintered bulks.
