We developed and reported the Single-Direction Melt Growth (SDMG) method, which enables the production of REBCO bulk magnets entirely composed of single crystal growth regions. Using the SDMG method, REBCO bulks consisting wholly of c-growth regions can be reproducibly grown. Applications of REBCO bulks include strong magnetic fields at mid to low-temperatures, such as for bulk NMR. Previously, we mainly reported trapped field characteristics at liquid nitrogen temperature. Here, we evaluate and report the trapped magnetic field characteristics of SDMG bulks at mid to low temperatures.
