Critical Current Properties of $c$-Axis Oriented Hg(Re)1223 Bulks

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 J

at 20 K and ~ 2.4kA cm

at 77 K in low fields, which are quite high values for Hg(Re)1223 sintered bulks.
